Navizon's P2P positioning system
Look, guy, not everyone has GPS, ok? Plus you know how much we adore P2P-whatever. Enter Navizon, a GPS, WiFi, and cellular peer-to-peer based mobile positioning system for Pocket PC devices. Of course, this system (like all other peer-based mobile software systems) only works well when you actually have a lot of people running the software, but they also claim to have the cellular/WiFi triangulation thing down by having those users who do have GPS sync to their servers with varying coordinates. Sounds like it could work—anyone want to take it for a test drive with a few of their buddies?
