There is only one Co-Op Map: Yavin

Yavin crashes for a fair amount of FS players (Vista + NVIDIA GFX card = crash for many)
The map is pretty decnt, but the AI is quite poor and there is very little balance. 

Last time I checked, DSGaming US Server was running this map non-stop.  The DS Gaming server is one of the few servers where the Server Autoupdater actually works, so it should be up to date if still online.

Until we get more co-op maps, and better AI, a co-op only server isn't possible.  Or it is possible, but it just won't be any good.

One thing stops Co-Op yavin being added to BI Rotation:, and thats the fact that everyone joins on the same team, our randomiser stops working and autobalance forces itself off. Thats alright for Yavin, but when it switches OFF of Yavin, we've still goto recover from those settings.

However, I've not had the radomiser tested when the Server switches off of yavin: It is possible that it will fix the teams and make them even itself.  Something to check out next time we've got a bunch of BI on.
