Yes I know it is not an easy task, but if Omnibot can be used in a game like ET with multiple player sets, and class-dependant objectives, It might be possible to do something for Tremulous. I don't have experience with waypoints and stuff about bots, but guys that make maps for quake3arena might have a small idea on how it works.
Anyway, the omnibot documentation is very good, and you can get an easy interface to create the waypoints inside the game, kinda like the sound editor system you have on ET (not sure about q3a).
If I have some spare time I'll try to see if there is any easy integration with the mod. Anyway I'm going to take a look at the bot system in the ETF game, and see if there is something alike or usable in Tremulous. But if you guys could spend a little time at it, you will probably get better results and faster, cause my programming skills are like "none"

See ya guys later
