As Andrew suggested, you might also check out placelab.org
<http://placelab.org/> a rather robust system for mapping wifi, and
geolocation, developed by Intel Labs and 'gifted' to open source.
The beauty of the placelab approach is the database of wifi ( and other
) beacons is downloaded to your mobile device so you can privately use
the onboard data to determine your location without querying a
[surveillant] network server. It's inherently "privacy observant"
