Couldn't you just clone the mac addy of a device that is connected already? I don't know as I have had no real need. I seem to always find an open WLAN when I have down time. In the city they are popping up all over and in the 'burbs just about every Dunkin' Donuts or bagel shop/cafe has one. Other than casual surfing, I wouldn't trust any WLAN that isn't a VPN because of the availability of information like this that can be viewed and used by anyone.
