Impressive, but I can’t imagine that anyone would refer to that scenario as “war driving”.
It's a screwy term. There's a Wikepedia page that describes the origin of the term here.
I'm still working on getting my 7 dBi 2.4 GHz vertical mounted on the highest point of my roof for a good 360 view. I'm interested in evaluating AODV and OLSR mesh networking with some of my ham buddies in the north end of Pocatello. It's almost OBE (overcome by events) as the Bridge Maxx people just installed WiMax towers in the north and south areas of Pocatello. Cheap, high bandwidth wireless is available now. There's not much point in establishing mesh networks to provide coverage with conventional 802.11b.
