One thing I will say is that I think too much focus is going into the bot AI instead of working on the engine's framework and functionality.
Uber Lieutenant,
BotAI is currently the only task on the TODO List that has someone working on it. BotAI is also a very important component of single player gameplay, so its good thing Smiff is working on it. There are other task that need programmers.
There is quite a bit of framework already provided with FPSNet. The code just needs to be broken up into code modules.
