I wrote a bit of code, using Luigi’s code for GameSpy in PHP, that allows you to query the gamespy master server and retrieve the list of IP and port’s for any of the GameSpy supported games.

This handy image –> [http://vengeance.za.net/servers/serverpng.png]
for example, is generated using the code, and is updated dynamically every 3 minutes.

The query code isn’t really cleaned up enough or ready for release yet, but you can mail me  if you’re interested in obtaining a copy in the meantime.
