another way to reduce/avoid clutter in the 2.4 GHz range, one can now 
easily get wireless phones in the 5GHz range. Haven't found a 5GHz 
microwave oven yet :)

WPA would be a much nicer option, but I haven't gotten that working yet 
under Linux. I'm not sure, if it's even available out of the box on in 
any distros.

By the way, the Security Focus article suggest, that with the current 
crop of cracking tools it only takes a few 100k packets to crack a WEP key.

and your neighbor has unprotected WiFi connected to DSL  :)
