Well given Android is (at least partially) open-sourced, is it possible to 
search their source code for their Wi-Fi geolocation API? Implement that as a 
loadable bundle to prevent licensing issue. (this CoreLocation clone can be 
LGPL so that this bundle, probably under Apache license as derived from Android 
source code, can link against, and GPL code can load non-GPL code to run or 
Linux will under dilemma)

And since we are searching code, how about tap into cellular geolocating (use 
cell towers instead of Wi-Fi hotspots) as well?

Or can we crowd-source the location information of Wi-Fi hotspots ourselves and 
set up our own servers for this? All this needs is pretty much a smartphone 
app, as it can allow users to submit base station locations using existing 
platform-specific location services. If I have the honor of implementing it, I 
will make sure it will remain free and open sourced.

Also, since we are implementing this, how about bring MapKit into this equation 
too? THere is an existing MapKit port to OS X that depend on CoreLocation using 
Google Maps API. I am not sure if it is useable with GNUstep (or mySTEP's) 
CoreLocation port.
