I've recently dove into python, and found a python module that lets you do stuff with quake 3 servers. Is the netcode in nexuiz for server variables, player listings, rcon, etc much different from quake 3?

Server status requests are the same as in q3 (afaik, i never had q3), but they don't include variables. Rcon is based on quake world, not q3, so q3 tools won't work. However both protocols are really simple, so it's just a matter of minutes to write such a python module from scratch

Feel free to use those ruby scripts as reference:

Right, you send rcon commands as a

"\xFF\xFF\xFF\xFFrcon hackme whateveryouwanttodo"

packet (in DP SVN, you can separate multiple commands by a \0) and you get responses as packets of the form

"\xFF\xFF\xFF\xFFnUnknown command whateveryouwanttodo"

That's all you need to know about the rcon protocol...

We're on a need to know basis...and damnit we don't need to know!
