See my original post. It's called a Diffie-Hellman key exchange, and allows two parties to generate secure keys while being eavesdropped. It's one of the coolest things in modern crypto.
I don't think that Slashdot qualifies as an ISP in this sense. I think it's more a matter of an ISP being a web-hosting site - is Microsoft's bandwidth provider liable for Sherman Anti-Trust Act-infringing Java VM's on their web site? No, because they're a service provider. Slashdot is a content provider - this isn't a personal web page but a discussion board.
I think that 'because I can' is more than enough reason to run Quake on it - and besides, you don't need much of a processor to pump out Quake at TV resolutions.
Multiple relays are possible - once you're on the network through at least one relay, you can get a list of more relays, and structure your network so that you're talking to the people with the highest connect speed. Basically, the modem users hang out on the fringes, while broadband users are clustered in the center.
The relayers know your IP, but don't know the request (it's encrypted).
The server knows your request, but doesn't know your IP (since it's been relayed). Transfers still remain peer-to-peer, you just need the IP of another client to get on the relay system. You relay packets for others and they do it for you.
OTOH Freenet does this, but it'd still be fun to do as a side project. Untraceability is a good, good, thing on both sides of the arrangement (because we never know who's serving those files, or who is donwloading them)!
(This is off the top of my head): There is not yet a polynomial order time solution to solve a class NP problem. The class NP-Complete is a set of problems that have been proven to be mathematically equivalent to each other (any algorithm that solves one in polynomial order time solves them all in polynomial order time). So far, the only solution to these problems is to enumerate every possible solution and then check for the correct one (like the travelling salseperson problem - you must enumerate every possible path and then choose the one with the lowest distance travelled.) That's also why there's such an interest in quantum computing (because they can enumerate all of those possible solutions at once!)
Any distributed file-sharing protocol that is non-encrypted is insecure in this fashion. The reason is simple: Your computer requests the serving computer for the file in question. The other computer obviously knows your IP, then, and a modified client can serve up that info. That's why the Freenet project is so essential.
Here's a simple precaution that can be taken when desiging such a protocol: One computer never directly requests to another. Instead, it gets a piece of information from the serving computer through the network (x, n, and x^y mod n for some x, y, n) and creates a key (x^y^z mod n for some z) and sends another piece of information indirectly (x^z mod n), so that the server can get this number (x^y^z mod n) itself. Then you can establish a two-way encrypted link securly while having your packets be passed through other clients (so that the server never knows your IP). (BTW the encryption is a diffie-hellman key exchange and is one of the neatest things in modern crypto).
BeOS is indeed nice, but a minimum version of the linux system is even faster - the main bottleneck being time to mount the ext2 partition. ReiserFS mounts much faster, so Linux with ReiserFS booting into 'linux single' is the fastest I can think of. BeOS is the fastest booting complete environment.
No, Slash is also tweaked to generate banner views. For instance, if you're not logged in (or just created a new account), you view in threaded, which means you have to click to view comments, insuring the maximum possible ad-views. The/. eidtors aren't dumb. They don't take the ad-gluttony to the max, but they sure now how to tweak a little bit.

How's e on your system? Tried KDE1.91 (it's sweet)? Considered buying an Accelerated-X driver for your card? I've had problems with Permedia 2 cards and XFree.
I don't think so. Bandwidth is expensive. Ratings were never part of the hard-copy media model, which to a certain extent the closed-media model is a copy of. But the 'net throws a twist into it either way. Open or closed, on the net, the Salon layoffs (which you made reference to, and I was trying to address) were part of an inherent flaw of the medium - that the number of eyeballs can be judged, and the medium can be turned into a TV.
To tie this in, I think the Open Media model is a recipie for disaster. Bandwidth is expensive. Advertising is needed. Soon, sites only posts stories that generate alot of interest. (Notice how the front page of slashdot is decidedly biased towards Linux. The editors aren't stupid - they know that they generate readings of the articles - and thus ad eyeballs by Linux articles). It stays "open", but it defeats the purpose.
You claimed that the Open Media model leads to links of all kinds of information. But that ain't so, because the ad-eyeball-phenomenon (as witnessed by the Salon layoffs) is a big problem. You end up catering to specific types of articles that generate the most interest from people, instead of covering it all. I think mixing content coverage and Open vs. Closed is mixing issues, myself.
But of course, I could be very wrong. (Thanks for replying to the comments. You seem to be more interactive lately, and it helps!)
Did you read the Time collumn about the Salon layoffs? He/she/it (at work, don't have the issue of Time) talked about how the Salon people were only layed off for failing to attract enough eyeballs. Is that the future of this new media? Will slashdot sites be the same way? (You didn't get enough comments, therefore you get the boot?) No thanks, I'll take my hard-copy of Time anyway.
First of all, I'd like to point out that Scot Hacker is the ultamite BeOS evangelist, who also wrote the BeOS Bible and runs the BeTips site.
On a more relevant note, the mp3asm tool availble from the MPG123 web site is a really neat tool to look at the source to - it'll show you the specs of the MP3 format right there. If you're at all interested in the down-and-dirty of dealing with MP3 format files, that source is a great starting point.
I think it's time you stop, now that you've just compared the Open Source/Closed Source movement with media. Step back, realize that not everything is related to this little political movement, (quite like the 60's movement, anyway). Then attack the issue again (which I'm going to do here).
In Time (this week or last, I can't remember) it was said that the Salon example was a foreshadowing of the state of new media - fired because the number of hits to the article wasn't high enough. It's almost like the TV-isation of journalism - just like TV anchors can be fired for not attracting viewers, 'net writers can be fired for not attracting readers (and thus ad hits). That doesn't happen in a traditional media format. I gets my subscription to Time, I reads the articles. You don't selectively browse a magazine, or read just parts "because you like the author". (Some people do, but that usually defeats the purpose - you bought the magazine, so at some point most people read it all). And nobody fired a magazine author for not being popular enough. That would manifest itself in other ways - writer isn't interesting, writer writes horribly. After a time, you get to know the regular columnists, whether or not you always agree with what they say.
The model of the new journalism is the model of the TV - getting rid of authors because their ratings aren't high enough, trying to attract eyeballs for advertising. It's not about openness. My static copy of Time is more vaulable to me than any article on Slashdot, simply because it's a well-thought out piece that's not incomplete without feedback (like this forum). And there's always a letters to the editor section.
Question - how does the Tivo display its graphics to the screen - is it X windows, or is it a/dev/fb0 program, or is it SVGAlib? Is it possible to hack this thing to serve as a remote X display, or (better yet) to run Quake?
...all CEO's have speechwriters. Jack Valenti the CEO didn't say any of that in the New York Times. Jack Valenti's speechwriters did. On the stand of the deposition he'll reveal that he doesn't actually know much about this or care - so long as he makes money.
I know this has come up before (prob. on previous discussion) but could the censorware company be sued for libel because of this?
Surely this is damaging the reputation of the school. Maybe we'll just sue the censorware companies until they go out of business (which would be nice).

No, I mean requests flowing across the network (and encryption to make it secure). If what I described were implemented:
See, it's perfect! All through the fun of the diffie-hellman key exchange.
