Major MMO Publishers Sued For Patent Infringement
GameboyRMH writes "The Boston Globe reports that major MMO publishers (Blizzard, Turbine, SOE, NCSoft, and Jagex) are being sued by Paltalk, which holds a patent on 'sharing data among many connected computers so that all users see the same digital environment' — a patent that would seem to apply to any multiplayer game played between multiple systems, at the very least. Paltalk has already received an out-of-court settlement from Microsoft earlier this year in relation to a lawsuit over the Halo games. If Microsoft can't fend off Paltalk's legal attacks, the odds don't look good for their latest group of targets."
I'm tired and going to bed but a quick Google netted patent 5822523. http://www.google.com/patents?vid=USPAT5822523

Seriously. The amount of prior art on this one is more than enough to keep these trolls at bay.
I am becoming gerund, destroyer of verbs.
Shared data creating a digital environment ... that could apply to Git, Subversion, Remote desktop, shell servers, IRC...
The good thing is that Blizzard should have enough resources to blow that patent out of the water.
'sharing data among many connected computers so that all users see the same digital environment'
Well there goes digital TV then....
this Paltalk company could end up making a LOT of money trying to enforce their patent. If they've already gotten a settlement from Microsoft, what's to stop them from doing the same to every company that makes an online game? They're already going after Blizzard and the others in TFA, but what about other companies? Would say, a company that runs an online poker game be a valid target? You *are* being shown the same 'digital environment' as others at the same time, even if it is just a poker table. It'll be interesting to see how this turns out.
Ah am not a crook! (\(-__-)/)
------ The best brain training is now totally free : )
Sadly its because of patent trolling, Oh well.
Anything can be found funny, from a certain point of view.
That way, there's actually something substantive to discuss.
When you can find prior art in the Jargon File, your patent is stupid.
Doom the first multiplayer video game using networked PC's came out in 1993 http://en.wikipedia.org/wiki/Multiplayer_video_game.
The patents were filed Patent 5,822,523 (filed February 1996) and Patent 6,226,686 (filed September 1999) I don't see how they could be valid.
does that patent try to cover file sharing by nfs?
seems that patent needs a review.
Someday we'll hit the human carrying capacity. And the band will just play on.
Don't most multi-user distributed systems (e.g. NFS) do that?
Sometimes it's cheaper to just pay off the plaintiff than to litigate. Blizzard has deeeeeeeeeeep pockets and has a reason to fight this. Let's see where this goes.
Non impediti ratione cogitationus.
Both seem to be about collecting a number of messages together and sending them as one parcel to a host in order to reduce the amount of network traffic and also to ensure that each host on a local group receives an update at an approximately similar time. Its a little like receiving a digest of messages periodically instead of getting them one at a time. The US Patent server appears to be a little Slashdotted at the moment - I keep getting Maximum Number of Users reached messages.

I didn't check the date of the pattent, but it may be interresting to check if MUD preclude this patent... Another kind of program that may preclude is some BBS doors and some programs that may have existed during the Spectrum/Commodore/Amstrad/... time
This is clearly after the first MUD (dikuMUD)... prior art ?
Patent 5822523, summarised:
The number of communications required to keep a game with N players updated with each other is O(N!). This patent suggests a method by which the communications are sent to a central server, with the server sending regular updates to each player of all the actions taken by the other N-1 players. The server includes the ability for clients to become part of a "group" which further limits the amount of communication required to something less than O(N). The patent attempts to claim the Nagle algorithm as a unique invention (ie: hold on to outgoing messages for a short time to potentially squeeze more data into one packet).
"Group" in this context would be similar to "instance" in World of Warcraft or "grid" in EVE Online.
If someone can explain how this is not an obvious solution to the problem, as evidenced by the parallel development of this technology by every MMO out there, I'd love to hear it.
The patent seem to be about reducing network traffic on multi-server systems, and having some way of aggregating messages to groups of clients. I think most early MUDs are single server systems connecting directly to clients and unlikely to be prior art.

If you read through the patent, it's basically the same as a mailing list that sends out digests. Trivial.
Back when I was doing my PhD, I (together with a friend) wrote a networked game called Xanadu (Xanadu - A New Adventure Dungeon Underground was the rather strained recursive acronym) for X workstations. We even connected across London from different colleges to the same server running on my Decstation 3100. That was in 1991, which seems to handily predate these patents. I still have a backup CDROM of the source code alongside all of my other (thesis) code ...
:)
:)
I remember pulling all-nighters in college, and I specifically remember the first time we successfully connected using the commandline client and moved a character from X,Y to X,Y+1, thus validating the movement routines - there were a lot of firsts for us back in that code: socket programming (thankyou Stevens), bitfields in structures, function pointer tables, etc. To see it all work at 3:00 am was a major high. Kid's stuff today, of course
Anyway, much as I'd love to think of myself as a prodigy, it seems this patent falls afoul of the obvious clause, and if blizzard or whomever want to get in touch for some patent-busting source code, just feel free

Can someone who is knowledgeable about patent law explain to me how one district in the US can be so appealing for this kind of ligitgation when another is not?
I was under the impression that patents are awarded federally, however it seems that the actions are being taken at a very specific locality which is widely considered more sympathetic than everywhere else, rather than a national or federal court.
This seems very strange to me, surely the legal position on a federal issue should be consistent across the nation. Or the verdicts across low level courts should be able to be 'moderated'.
If this were really happening, what would you think?
And in a good example of previous art, MANY years ago, I used a chat program called "powwow" (yes, created by the Native American community), that not only allowed group interactions, but, had shared games, and the ability to surf the Net as a group (one URL click would take the entire group to that website) and many other group interactions.
Since this pedated paltalk, I suspect that the awards should go someplace BESIDES into their pocket.
here are some comments about Powwow....

Wouldn't any server/client system be affected? Any database? Or does it have to involve graphical representations of the data? Why is that distinction important?
I already claimed a 1 to infinite recursion of the patent patenting patenting .... patent.
Sorry buddy.
(Oh, I also claimed the infinity + 1 recursive patent)
((I also claimed the grammar nazi patent. "a 1" is correct because you don't use "an won", for won is a homophone to one))
I suppose the real question is not if they can be sued, because of course anyone can sue anyone, it's whether or not they would have a case to answer, specifically because software patents are not valid in the UK. I understand that there are some minor exceptions to this rule, however I don't believe this patent falls under any of them. This will be very interesting.
I was at the University of Essex from 1982-1985 and I sacrificed all my mainframe time (meant to be for study purposes) to play the original MUD which started in 1978. I didn't read much of the two patents as the patent server seemed slashdotted, but they seem to be about reducing network traffic and also trying to get clients to see the same thing at the same time, and they don't seem to apply to single server, multi-client systems but to server network, multi-client systems instead.

The thing I dislike about patents is that it is in the self interest of their creators to make them unclear, obfuscated, and multi-layered in a way that means that even if the clearly over-general claim quoted in the summary is rejected in a court of law, the patent will still retain most of it's value. Having previously worked under them, will be interesting to see how Andrew Gower and Mark Gerhard deal with this.
Sounds quite a lot like quiz games over IRC to me.

As usual, Slashdot's summaries are the "OMG, here's a broad mis-representation of the patent, so we can whine about it" trolling. I swear if someone invented a new clock mechanism, it would come out on Slashdot as "OMG, they're patenting the cog." Because apparently some people just try that hard to belong to a big family of clueless whiners.
Actually searching for HearMe's patents (since TFA mentions that the patent was bought from HearMe) actually shows that they're a bit more speciffic than "showing the same world on two PCs". Not by much, mind you, but still. So the actual debate would be whether it's a multiplayer game, but whether it implements the exact synchronization algorithm described there.
And if you want to help those companies, knowing what they need help with, might help more. And just "it was a multiplayer" game ain't it.
The actual patents that seem even remotely relevant are these:
1. Method and apparatus for loosely synchronizing closed free running raster displays
The problem is that I can't see how it even remotely applies to multiplayer games, except via an equivocation fallacy. It's about "seeing the same thing" in a much more literal way: literally seeing not just the same scene, but the exact same image and synchronizing the frames. As in, the VSync signal comes at the same moment.
I don't think any game does that at all.
It includes such tidbits as temporarily changing the video mode to interlaced (which should look the same, according to them -- except to anyone who isn't blind, it isn't), to change the timings on one monitor, then switch back to non-interlaced when the sync signals synchronized with each other.
Again, I don't think any actual game does that. I don't think interlaced modes are even used at all nowadays.
The second problem with it, is that it's been filed on 23 December 1997, i.e., a good 3 months after the launch of Ultima Online. So if they actually want to push the "it's about seeing the same thing" equivocation, it seems to me the defense doesn't even have to go as far back in time as your Xanadu. UO already showed the same thing.
2. Server-group messaging system for interactive applications
Basically this one is about this: you have a server and X clients, and all clients are sending packets to all other clients. Think, an IRC channel, basically. So they propose that instead of dumbly routing between clients, the server aggregates the packets and sends the aggregates periodically.
The first problem is that a MMO only does that in a very loose sense. It sends the resulting status, rather than the bundled messages from all other players.
The second problem is that even if they want to push the equivocation that that status processing is a form of aggregation, MUDs already did that. Whenever you entered a room and god a "PrincessLayMe and MrMacho are standing here", it was effectively an aggregate result of the previous movements of the two players.
Of course, this has the caveat that their patent actually mentions aggregating over an interval, and sending the status periodicially, which MUDs did not.
However here comes the third problem: the patent was applied in 1999, a solid two years after UO which _did_ do just that.

Microsoft might not want to "fend off" some legal attacks... by paying a settlement, which they can easily do, they give the trolls the means to attack others who might NOT be able to afford a settlement, thus clearing the battlefield, err, market, for Microsoft's products.
I have no idea if this applies here, but this isn't cynicism... Corporations DO think this way. There is no morality involved, only the logic of competition in the markets, and there are no questions of legality, only those of court and settlement costs vs potential profits.
Can anyone tell me what effect the stupid US software patents system would have on overseas developers where there is no software patent law?
If an MMO developer like Blizzard were based in Europe could they basically tell them to fo, or would they still be able to bring a case and prevent them accepting paying customers from the US?
Clearly this kind of suit severely impacts innovation- what indie would dare try and develop and online game if they're at risk of being sued or forced to settle such that they can't afford either? I'm intrigued to know if the impact flows beyond the US and impacts overseas developers too or if they can simply say "Sorry, your patent doesn't apply in my country, get lost"?
Any clarification on how the US software patents system affects us outside the US would be much appreciated.
While I agree with your sentiment, the problem is not exclusive to the USA. Every country seems to have a large number of people who are very impressionable and don't think critically enough. These people don't read enough books/articles to develop a well grounded worldview, and attempts to enlighten them are almost always futile. If half the country thinks it would be a good idea to elect Bush twice, what exactly am I supposed to do about it? If I was Venezuelan, what do you recommend I do to get rid of Chavez, or Castro, or the Chinese Communist Party? Even if most Iranians would rather not be ruled by the Ayatollah, it's not like they have much choice in the matter.
Assholes rule over idiots, it always has been that way and always will be. The only way to make a better society is to educate people to the point where they are capable of telling the difference between assholes, idiots, and smart well intentioned people.
There will be lots of major applications that use client/server architecture to manage data for clients before that date, "Exchange mail server" or similar software should be very much covered also (no time to study the patent though). Microsoft or Activision law team should pursue invalidation aggressively, such patents are just too dangerous, not to mention the trollie surely has no real world application for this.
Patent 5822523, summarised:
The number of communications required to keep a game with N players updated with each other is O(N!). This patent suggests a method by which the communications are sent to a central server, with the server sending regular updates to each player of all the actions taken by the other N-1 players.
So far it sounds exactly like how a MUD works.
The server includes the ability for clients to become part of a "group" which further limits the amount of communication required to something less than O(N). The patent attempts to claim the Nagle algorithm as a unique invention (ie: hold on to outgoing messages for a short time to potentially squeeze more data into one packet).
"Group" in this context would be similar to "instance" in World of Warcraft or "grid" in EVE Online.
I'm not familiar with WoW or EVE terminology, but is there any chance that this might be similar to a "room" in a MUD?
Just to clarify, after reading the patents a bit, HearMe does look to me like a bit of a patent troll or potential patent troll. Everything reads like the kind of guess about what a game might need, by someone who never actually programmed a game.
E.g., trying to sychronize the VSync on two computers seems such a profoundly useless and counter-productive thing, that it boggles the mind. Let's just say it would prevent the following 3 people from playing together:
- Tom, who has a 60 Hz TFT
- Dick, who plays on a CRT in 85 Hz
- Harry, who bought one of the new bundles of NVidia 3D glasses and a 120 Hz monitor required for it
It's not just that any synchronization in the sync signal would last exactly one frame, it's that forcing the 3 computers to display the exact same image would prevent Harry from getting any stereoscopic 3D effect. (He needs alternating frames rendered from slightly different view points, which the other two don't and it would make them see double if they did.)
E.g., just collecting and routing aggregates is
1. Useless in that literal form not only for games, but for IM clients too (which seems to be all that HearMe actually did make). If the messages in a chat room are that fast that you gain anything with an aggregation time so small that it's unnoticeable to users, then it'll scroll too fast to read anyway. And if you aggregate over several seconds, it produces abrupt chunks of scrolling that actually are disruptive and annoying.
2. Already done pretty much anyone who ever wrote a batch job that runs periodically. And I'm pretty sure that, for example, that FidoNet already worked that way.
Ah, wait, they have the patent troll "over the internet" clause. And FidoNet wasn't over the Internet. Sorry.
Well, even then I'm pretty sure at least some mail servers and NNTP servers work exactly that way. For a backbone system, the mail or news servers down the line are the "clients", and it aggregates the mails or news items instead of routing each individually to each client.
A polar bear is a cartesian bear after a coordinate transform.
My first thought was this is great anything to force innovation. Something more then the same old, same old in MMO gaming.
But then again sounds a bit broad, as do many a patent these days.
On the other hand, an online game where none of the players would share the same environment would be more challenging !

He should have said "zone" in WoW, but yes. Same thing.
That was the real time sink at Data General in the early 90s. Played over the internal TCP/IP with Sun workstations.
Obviousness though it should be a defence is abhorred by lawyers for it's complete subjectiveness and has been driven out of the patent system altogether, and to a jury in Texas very little is obvious. Gaming the patent system is about finding problems no one has thought about yet but which will become relevant soon, the solutions will be trivial but because the problem is not one currently relevant no one will describe the solutions ... the solutions will thus be novel, and that's all the justice system cares about.
AFAICS these people succeeded.
Obviously everyone has forgotten DECWARS, MUD1, Island of Kesmai, etc.
The patent is invalid. That Microsoft chose to "settle for an undisclosed sum" according to TFA (because of HALO) only encourages these idiots - in fact, that's probably what Microsoft wanted... it takes the heat off them and puts it on the other guys.
When oh when will the USPTO learn how evil software patents can be, especially vague ones like this.

Actually, we're talking about the same MS which bankrolled at least a part of SCO's lawsuit against IBM. Including, yes, by buying their bogus protection racket licenses. Funding yet another troll that could hurt their competitors more than it hurts them, is exactly what I'd expect from MS at this point.

Well, for you it may be as simple as that, but you can't go in front of a judge and just say that you don't believe in software patents. So until such time as it changes, looking at exactly what a patent says is actually a pretty good idea. IMHO.
A polar bear is a cartesian bear after a coordinate transform.
If you read through the patent, it's basically the same as a mailing list that sends out digests. Trivial.
While there have been "mail" games running through mailing lists for a while, MUDs would be a much more pertinent comparison. There have been MUD servers pretty much since someone figured out that you could telnet to any port and stick a server that did silly things on there (or in other words, since the 70s). Everybody who was around in the 70s or 80s had a few MUD accounts, if only to see what all the fuss was about.
It should be trivial to shoot this one down in flames (which assumes the lawyer understands what he's talking about and the judge understands him, fairly optimistic assumptions...).

I am looking forward to seeing how this is going to pan out, sure MS probably gave in, because they helped push the patent, so they want to help enforce it...even though there is no proof for the public of this fact. I am sure that there is a sort of under the table dealing here, where MS will end up owning this patent, and being that it was enforced somehow through misdirection on their own part, and the likes of blizzard etc..would follow, the future of this type of game, will be great for MS!
I hope the likes of blizzard and the rest of them, band together to form a sort of counter to the lawsuit. Hopefully by pooling their resource, they will be able to find a loophole should this thing be somewhat legit. Good god, I would hate for them to start asking us to pay even more to play WoW because they now have to pay royalties.

This doesn't actually mean a game instance or a dungeon instance. This means the players join a group from a network perspective.
The end result is that I join an area and after joining I share to all other clients that join the same area. Guess what, that's not how the mmo's do it because it introduces cheating and potential for me to disrupt another person's gameplay.
I'm pretty sure that Torrents would have been a better goal for this a-hole.
Zarni Maung shows a long history of accepting broad reaching patents that sadly affect almost everyone in everyday life. Back in 1996 I'm sure it was difficult to see what would happen with all of these idea's but some of the patents accepted by Zarni Maung help to define the internet itself. Also all these companies just need to find examples of prior art to 1996 correct? The other question will be if any other past MMO creaters were sued or paid licensing fees to the group that holds this patent.

It strikes me that this is yet another case of "company buys patent from somebody else, company tries to sue people with their new patent." It really is quite abusive, seeing as patents are there to reward innovation by inventors, but I think I've figured out a simple and elegant way to prevent this sort of thing.
Make patents non-transferable.
So, the only person or organization who can sue somebody for patent infringement is the one who actually invented the thing. That might not knock out every patent troll out there, but I'll bet it would wipe out the majority of them...

Mine was Microsoft settled with SCO as well, so I'm not surprised that they settled. It is not that Microsoft can not fend them off but they just don't care enough to fight it. I do wonder who is going to fight it.
If I were looking for prior art on this one I would look at SIMNET (http://en.wikipedia.org/wiki/SIMNET) I would look at the systems leading up to it and the follow on systems. DARPA was way out in the lead pushing for distributed VR systems in the '80s and early '90s.
OTOH, I did skim the patent and it looks like they are talking about sending packets at fixed time intervals. The packets would contain all the little messages generated for the recipient during that time interval. That is a clever idea. Almost, if not exactly, like accumulating the motion of a mouse or a joystick for fixed time periods and reporting the accumulated change at fixed time interval. Something that device drivers have been doing for a very long time.

If you read through the patent, it's basically the same as a mailing list that sends out digests. Trivial.
Actually, it's not *basically* the same. It's *exactly* the same. Almost every claim has prior art in standard mailing list management software that has existed practically forever.
I was thinking IRC + Nagle's algorithm as prior art, but I think you've hit the nail on the head there!
I'm not familiar with WoW or EVE terminology, but is there any chance that this might be similar to a "room" in a MUD?
Yes. Or a channel in IRC (as the patent isn't phrased in terms of a game at all, but a general communication system).
The only thing is, every claim in it depends on updates from multiple sources being batched up and sent to clients in a single packet. I don't know enough about MUD software to be sure this was done. Nagle's algorithm makes it an obvious thing to do, and means it must have happened at least by accident, but did any MUDs intentionally do this? Or IRC servers?
MUD1 was the first MUD, DikuMUD came a few years later.

You missed his entire point - he wasn't claiming IRC, he was claiming a method of delivering goods. Does IRC deliver baked goods? Then IRC being a 'general purpose communication medium' is irrelevant.
If a method of delivering baked goods using the telephone network was already known, why wouldn't replacing the communication medium with another well-known communication medium be obvious to one skilled in the art?
Actually, no. TFA says that Paltalk is suing based on two patents (not one) which, according to TFA relate to "technologies for sharing data among many connected computers so that all users see the same digital environment." TFA does not say Paltalk has a patent on "sharing data among many connected computers so that all users see the same digital environment." Confusing reports of what the patents relate to to what is actually covered by the patents is pretty much a universal rule for Slashdot patent stories.
According to a source with more detail, The patents involved area series of patents (apparently, not just two), including US Patent 5,822,523, which covers a "Server-group messaging system for interactive applications", and several others that build on the system in that patent.
What about things like BSD's Talk? Doesn't that basically do the same thing? Doubly so for ytalk, etc. They allowed for 'sharing data among many connected computers so that all users see the same digital environment'
Bark less. Wag more.
Well Atari had the JagLiNk http://www.atariage.com/controller_page.html?SystemID=JAGUAR&ControllerID=22 for the Jaguar that connect two Jaguars to play head to head. The story didn't say when the patent was originally given but the JagLink has been around since 1994?.

I agree with you, it looks very weak to me. As I understood it when I was a child, the universities and such dealing with virtual environments (3d worlds) obviously wanted multiple users to share the same environment and experience the events/occurrences at the same time, just like in the real world.
It seems to me that this patent completely fails the obviousness test with MMOs are VR Worlds.
Here's hoping the judge smacks them down.
Do sci-fi stories I rad in the '70s with multiple people sharing a virtual computer world count as prior art?
(-1: Post disagrees with my already-settled worldview) is not a valid mod option.
Damn, I knew I should have patented "Something that shares data with something else to do stuff".

It's not only good for the medical industry.
This patent seems to be about a way to keep big distributed game systems from choking on O(N^2) traffic. There are other approaches; it's not clear that this one is widely used. Current practice is, I think, that clients send to the servers, and the servers send back updates to the clients that only contain information relevant to that client. The method described in the patent works more like a LAN party, where everybody is multicasting to everybody else.
The mechanism described in claim 1 might apply to multiway voice chat. That's exactly this type of problem. If you can only talk to the people "near" you, you need just that kind of distribution system. If player are in positions where A can hear B, and B can hear C, but A can't hear C, you need the kind of aggregation described.
Better voice systems are way beyond that. I went to a demo at Dolby Labs where they had multiplayer positional audio with proper attenuation and occlusion as the players moved around. As a demo, they had a player move entirely around the audience, while talking to someone who wasn't moving, and it all sounded right. Thinking about that, though, the audio processing was being done in the receiving client (to construct five channel audio, phase-synchronized, you have to do it there), so probably the message traffic was simple aggregation, plus positional info.
One of the main characteristics of the game 'Aviator' on SunOS (developed by Bruce Factor and future nVIDIA co-founder Curtis Priem) was that the protocol was designed such that mutiple client computers all had a consistent view of the shared flight space, with no central authority. There was a white paper on the protocol that made very interesting reading (back in 1990), I wonder if any copies are floating around somewhere? You can still find references to the protocol out there (look for RFC1340 and the IPv6 mulicast assignments doc: RFC 2375.)
I have fond memories of playing Aviator at Sun -- my favorite was the X-29.
All Software patents are obvious on some level. I still think software shouldn't be patentable, only copyrightable.
I'm a developer, and I still feel as though writing a program is similar to writing a book in that regard. If you allowed publishers to patent ideas for books and methods for main characters to traverse through the story, you'd basically hit the same point we are in software patents. Dragons would be patented to someone, Mystery Novels would be patented to someone else...
Every time I start to have faith in humanity, I ruin it by driving to work between 7 and 8 am.
I once programmed for and was an admin on a mud that actually had some functions / mini-games which used 'aggregation over an interval' and 'sending the status periodically' (ansiblemoo.org) The code was written this way partly to save bandwidth, but also to just keep that part of the game orderly and fair for all players, regardless of connection speed. It meant not spamming the players every second with soon out-dated information, and the delay also meant that players couldn't simply hammer their keyboard into victory. I think this effectively covers the patent... The code in question was first completed in 1995... or something like that - before my time (and the patent's) - and other similar code was written from 1996 through 2002/2003.
If I'm reading correctly, the patent mentioned was filed in '96 and issued in '98. Warcraft 2 came out in '95. Good game?
I already claimed a 1 to infinite recursion of the patent patenting patenting .... patent.
Sorry buddy.
I, for one, would love to see some transfinite ordinal numbers in spurious patent disputes! If they're not going to go away, at least make them entertaining.
And immediately think of IRC, TPC, Nagle's algorithm, and delayed ACKs?

IANAL, but it seems to me that if my server collects messages and then merely writes them to a socket using TCP, which buffers the messages, aggregating them into chunks of size MSS, then sends them as a single segment, I've violated this patent.
Did these guys patent IRC? And did Microsoft pay for it?
I'm probably a little rusty, but isn't this problem O(N^2)?

Doesn't seem to speak about seeing the same digital environment.
If Google really cared they would fix Android Chrome to reflow text, instead of discriminating
"Group" in this context would be similar to "instance" in World of Warcraft or "grid" in EVE Online.
Actually, World of Warcraft limits what data is sent to you by distance, rather than an entire instance or "zone" etc. In EverQuest 1 they originally sent all of the data for the entire zone (to get an idea of size, some zones would take more than 10 minutes or more to cross), which led players to develop tools like ShowEQ and MacroQuest, which would obtain the information for everyone else in the zone and display it to the user. If you were looking for something rare to kill for the phat lewts, you didn't need to be anywhere near it. So, besides the obvious bandwidth optimizations from limiting to a smaller area, games that intend to sell well will typically limit the distribution of information in order to help prevent various types of cheating.

if you STILL dont know that, that's the word to describe you. youre just another ignorant american.
check scandinavian countries. while local sheriffs are wanting to expose those who criticized on the net in america, in sweden the individual freedoms issues are at the level of 'whether swedish women should be allowed to not wear a bra in public beaches'. which, the women has won, and a court decided that it was inalienable right to be topless.
this should demonstrate how sorry a state you are in.

no other country harbors enough evil on its top ranks of administration and economy as america that they actually go try to infest other countries. this happens only in america.

But almost all the old implementations (mudlibs), not just LPs, DIKUs or MUSEs, have some sort of chat channel system, limiting messaging between players. These are, as mentioned before, much like mailing lists, where players P1 and P2 are member of a guild level range or ad hoc group (gangs, party etc.) and get only messages applicable to them.
Further on there is often an option of filtering messages by type, so that P1 gets the info about mob M1 hitting P2, but not M2 hitting (on) P3. How old the oldest is, I have no idea, but on one LPC implementation I find a (C) VikingMUD 1993 in the channels.h file, but the channel implementation is probably based on something way earlier, like http://www.genesismud.org/
