I am in Torbay at the moment and have used Kismet and Wardrive Android to cover a bunch of locations around the bay as well as some trips to Exeter and Plymouth and the odd trip across the country to my fokes place
I am curious to find out what the commercial use of Wi-Fi location being employed by Google (in the Android Google Maps My Location) and Skyhook will do to this hobby. At a guess they are both just going to plug into the open databases and use them as a reference for their own systems.
Hope you are all doing well, if I can be a help then drop me a line.
