Skyhook stuff is good. Not only do they do their own collection of SSID/MAC/GPS data, but users can also choose to submit their location data. That is, using the Loki tool, you can update your location into their database. Using this user-generated data, I was astonished to see that Skyhook got me to within about 30' of my actual location via WiFi geo-location. Very cool stuff.

This is the same technology Google is using in Google Maps Mobile and on the iPhone, so it's definitely ready for prime time.

Can't wait to see what the ITT community can do with this.
