Geolocation of IP addresses isn't the most accurate of things, but it
should be enough to connect the majority of users with a broad
geographic region. There's an opensource database and set of APIs out
there called GeoIP by MaxMind which you may be interested in:
http://sourceforge.net/projects/geoip/ or
