Hmm, still have no idea about the name of the project i'm working on.. On the other hand, server script in Python works perfectly, i've killed some bugs here and there and it's working fine.
The things currently implemented in the server are very limited. There's no authentication method at all, and I'm still thinking about the correct way to deliver neighbour information to clients. In current implementation, the client has to be connected to the server at all times, sending GPS position information at specified intervals. The server hits the client with information about locations of all other clients as soon as the client reports his location - which is rather dumb :).
I wonder if I'm reinventing the wheel here...
