Coveting Thy Neighbour's Wifi

I returned home early the other day to discover I'd forgotten to pick up my house keys and that Fiona was out. So, sitting parked up outside our front door I took out my notebook and scoured around for an open WiFi access point, and duly found one. One of my less security concious neighbours leaves his connection open and connected to the web. What a nice chap, inadvertantly. Don't even know who he is, the access point was just called Linksys. Wardrivewaying.
