I am in the process of developing a city-wide wireless network. Here are some of the thing I am doing in my lab to prepare for rollout.
1. PPPoE Yes its anoying to users, and I'm not to fond of it myself, but it is a hell of alot better than any other auth method, IMHO, and it allows me to do some cool stuff with radius.
2. Amps are your friend Most interference can be weeded out just by drownding it out. Pick a channel, and stay with it, when and if you have problems with interference amp it. Other devices that don't need as much as a spectrum in the 2.4 range, such as phones will just look for another clearer channel. At the ITECH i beamed in a signal into the convension center from a nearby hotel and ran an IP phone over it, I found out the morning of the show that lots of other people were using wireless inside the building, i just ran up to the roof of the hotel and stuck on an amp, and bamo 11Mbs, nailed.
3. Channel Selection Most devices i've played with will either defaul to channel 1 or 6, put your signal on a high number like 9 to avoid killing your clients internal wireless network.
4. Saturation The one concern I had is saturation, with only 11Mbs on 802.11b several power users could suck up alot of that. I would expect that more technical clients will realize that they are on an ethernet segment together and start setting up shared folders for their buddy 2 doors down so he can get all of his mp3s/porn. with enough users it could turn into a problem. I am remiding this by creating a backbone of 802.11a and then distriuting it with 802.11b
You know its stories like this that really make me wonder what kind of morons are running the show over there.
They can do all they want, rally behind a format, develop a new one, encrypt things what ever. It doesn't matter.
Lets asume for a sec that DeCSS doen't exist and there is no way to play a DVD on linux box. Ok if I wanted to copy a DVD to send to someone what would I have to do. I would hook up my DVD player to my TV Tuner card and capture the stream. Duh!
These dude are never going to be able to copy protect anything because to do so would make the product so dificult and inconvient to use that the average consumer wouldn't buy or use it.

How do you disable checksumming on a TCP packet, oh that's right you can't.
If the checksum is not there or doesn't match the data, the packet is droped.
Yea it Sucks if your not intellegent enough to learn how to use it.
If you need your hand held with a start menu, and have to use wizards for everything Linux is not for you. Stick with windows, if you don't mind rebooting every now and then then that's great.
Stay with what works for you, if you don't mind being tonld how your desktop will function.
Gnome is totally customizable, you want a menu bar, you got it, don't like any icons on your desktop (like me), you can do that too. Try deleting the My Computer Icon in windows, I'm sorry dave i can't do that right now.
When first switching to linux, yes there is a learning curve, but eventually you will realize the power gnome and other desktop environments give you.

But the average MCSE is not capable of setting up a novell network either.
Lets compare apples to apples, I'm a linux user so i am skilled at both typeing and clicking the mouse. Therefore i can vim my/etc/*.conf files in linux to speak to my windows cluster that i set up by clicking my mouse.
At the root of it all (pun intended) is concepts, if you can understand how SMB works based upon domains and workgroups, you can set it up in either environment, it just depends on how easy that environment make it. Linux is less userfriendly (right now) to people who do not understand the underling concepts.
besides, no one can set up a windows 2000 network in just a few hours, it takes a few hours just to install windows and secure it down to the point where you can configure it for your network.
Or do you jsut install it and trust Microsoft's defaults, i hope not, that's just being uninformed.
ok here's the deal with the price going back up, i used to work for tech support so i had billions of these questions when they first dropped the price. The original price of the iopener was $399 in November of 99, then they dropped the price to $299 for the X-mas holidays. Then they had a Super bowl comercial that advertised a $199 so the price dropped again, they started selling so they dropped the price to $99 around late feb to try to flood the market before the other i-appliances got in. After Fathers day the pric whent back up to 299, and i guess now there is a such a demand for the POS that they are going back to the orig 399 sticker price, they are still loosing mony on it since its about 600 to make. Oh yea by the way, i tallked to a few of the hardware guys over there before i quit, seems that they are starting to think there are some seriour hardware design defects with thte modem, go figure, about 80% of my calls were i can't connect Issues.

just my $.02
ATI does not support any of their consumer products under linux. However the GATOS Project supports most function under linux, including the remote.
