livejournal.com has two comms I know of for wardriving. war_driving, and wardrivers. for your pleasure. Though I know of no good linux ported wifi scanner apps as of yet to windows/xp. Airsnort looked like it had a port, but the two ports available don't work. My suggestion:/ Install a small linux install:D Like partition magic a 500meg partition, and add gentoo small version. I know it's like 80 megs. I don't know however how big it extracts to.

Yea Netstumblers is nice. For Pda there is something called MiniStumbler But I prefer PocketWinc.

Kismet does own for unices, and linux flavors. Unix variants are great for software. I trust kismet.

Netstumbler is not going to be able to detect APs with broadcast SSID disabled.
