Ok so I know this reporter was not speaking about Enterprise Ip PBX solutions. But Cisco, Spectralink and Symbol have shipping Voip wifi solutions that are used by thousands of corporations worldwide. It's not cheap and it's meant just for use inside the enterprise. But the technology is proven and heavily used. The article seemed to imply that the technology wasn't ready for prime time which in fact is contrary to the experience of many enterprise users.
The pols are always telling us how broadband roll out is critical to our economy so why is this a bad thing? Of course out of one side of their face they talk about how important broadband is and out of the other they help the media industry clamp down even further on online distribution of content. I hope they understand the killer app has already arrived, the answer to every broadband providers dream, a bw sucking app everyone wants and will pay a bit for. But the media companies need a little shock to the testicles to get them out of bed and in the game. Instead of the FCC repealing mandatory line sharing to help incent the telco's to deploy broadband (of course repeal line sharing makes perfect sense, idiots). Why not provide incentives to the media company to distribute content online? This will take care of all the broadband deployment issues overnight. And we can stop worry about what people are doing on P2P networks.
So if I don't want any B clients on my networks all G max speed. But maybe my neighbor has an entire B network that overlaps from an RF point of view with my network? If I turn off the compatibility mode will I sink his B network?
Why not get someone to sponsor the network without banners? Like the city or a deep pocket local corporation? You could use something like nocat to force users to see the name of sponsor and get them to agree to the AUP when they startup. But after that access would be unfettered. This model has worked for NYCWireless.

The NYCWireless.net group recently decided to pass on the opportunity to be part of the Boingo database. The group sentiment was that Boingo and other similar companies would need to show some goodwill towards community networks in the form of sponsorship, open source software or free access to their commercial "hotspot" AP's.
Personally I don't think there is viable business model. Free community networks and/or self organizing mesh networks (with commercial and free internet on ramps) are going to survive the test of time.
One of the reason that UltraSparc kicked the crap out of Intel P series chips is that that intel chips are 32bit and the UltraSparc platform is 64bit. A similarly clocked Itanium and US3 is going to compete in the same performance range because they will both be 64bit chips. The old rule of thumb that a Sun chip is twice fast a similarly clocked Intel chip is history.
For person to person phone calls, when designing Voice over IP network the one-way delay budget is 150ms. Beyond that participants begin to speak over each other, like you would experience when speaker to some that is on the other end of call that is routed over a satellite.
If you have never run the tech team for hosting company and been asked by management to put aside your convictions to support a large $$$ customer. Your not $$really$$ going to understand this post. The courts have yet to set standard that really addresses the harm done by most spammers. MAPS as grass roots effort by the sensible none greedy people running the gear is logical out come of this gap in public policy. MAPS is the results of the sensible, spam is result of the greedy, choose your team and start running.
I find it hard to believe this Geo database is accurate.
1. First of all registration data about the location means nothing since an ISP registers everying via their home office. Even though the IP addresses are used world wide.
2. Measuring packet delay from known point, well there are million reasons why this approach will not work. Take your pick.
3. Trying to break down and interpet the symbolic names assigned to devices in the path to the device. Some ISP use logical city abbreviations and some don't. There no standards in the space and I don't believe someone read every traceroute.
This area of technology is so full of hype and marketing lingo it is hard to sort fact from fiction. Are they first? So what tomorrow someone else will be second with bigger this or that. I would not attach too much importance to the fact that a reporter got duped in to believing this was the "holy grail".
But it is so interesting that optical switching has become the rock star of the day. Because essentially these are very low intelligence switches that perform very cool optical tricks. These devices are essentially circuit switched devices. But even that is probably too much credit they are static circuit switched devices. Because optical paths are setup by a network administrator. An IP router or carrier voice switch are far more intelligent then one of these devices. No one gets excited about add/drop muxes anymore but I am sure in their day it was big deal. Add/drop muxes became a commodity, just as optical switches probably will become some day. These devices, along with IP routers, ATM switches, ethernet switches, sonet muxes, dwdm, etc... are low glamor working class equipment of the carriers networks.
The most interesting part is the ability split out or splice in individual wavelengths, neat trick.
For several years I was part team that ran corporate web proxies for 30,000 employee firm. There was at the the time not a policy against using web based email. But in one incident I can remeber we did review proxy logs in attempt to determine the source anonymous email that was directed at employee. We did so by searching the log for logins to web based email system that happen to have userid in url. It was an effort to determine if email was actually from another employee. We never had cause to sniff the entire http activity of single user. But we could have with little effort, and would have if directed by HR.
Well it means something if someone goes to Ip address and demands to know who the customer using that address is. Of course I am not sure under what condition and ISP will release that information.
I cannot imagine how with gnutella they could get anything but your ip address. So even if they went through the trouble to get name to go with hundreds of thousands of ip addresses, which is too costly. Who would they complain too? Gnutella has no head, or it has thousands of heads. Either way there is no master control switch to turn off. Just the courts.
I don't get why this would be useful. As far as i can tell firewire has only be implemented for connecting peripherals to cpu's. Are you suggesting doing system to system networking with this technology? Interesting but then it just ends up being ethernet all over again all the same problems withOUT 20 years of making it work. I have had similar conversation about fiber channel. I have noticed a number of people not directly involved with networking think the problem is the current technologies. Well your correct, but the answer could not possibly be to replace them with something brand new. Most all new datalink technologies like fiber channel and firewire offer similar capabilities as Ethernet/fast e/gig e. But mostly lack deployed standards and all the features need to deploy to thousands of nodes.

No shit your US3 is 64bit and the Intel P machines are 32bit. RISC vs. CISC is not giving the biggest performance boost the 64bit architecture is.

Why would the boss need to know how to do the sniffing? He can just order admin to collect the traffic.

Of course I ment "goes to the ISP" not "goes to the ip address".
Well it means something if someone goes to Ip address and demands to know who the customer using that address is. Of course I am not sure under what condition and ISP will release that information.
What documentation must someone turn up with before you will release the customer identity associated with an IP address?
I cannot imagine how with gnutella they could get anything but your ip address.

You are right on target with Globalcenter I feel I spend half my job fighting with GC about peering problems with other carriers.
I do not claim to know everything about every provider. But they all seem to suck. I consider my job figuring out which one sucks less.
