All botlib syscalls are back in and working fine. Bots can be added and join alien/human team. The behavior isn't implemented yet, so they don't spawn just yet. I'll report here when I have the first bot to spawn.
Post a patch when you've got something.
I think, actually, a different approach might be easiest. Here is my idea: Create a new class for the AI (yes, give it its own model too!) on humans and aliens. Because the AI is very likely to be retarded, give this new class advantages to balance out the deficencies. If all AIs have the same size, you only need to run a pathfinding algorithm on each map once (though botlib does this, no?).
For the human team you could probably create, without too much hassle, a kind of walking turret. It'd be capable of using a few weapons (hitscans probably), and would run some kind of simple strategy. Give it lots of HP and make it fast and it might even be useful. 
Say, Ris, sorry to butt in since I'm not going to actually code anything, but:
This is a really hip idea for a n00b botmatch thing. Somebody else mentioned medical drones. So, thinking along the lines of the Deus Ex drones, you could have various classes. And, Quake3arena already has the proper bot behavoir (Giant Eyeball, except it would be looking for the rocket launcher and the flag).
Thematically, you could play as either Human or Alien against it, because Humans would use them to train, and Aliens would use captured ones to train also, or just meet bots in forward areas where people haven't been sent yet, or in areas that have already been "secured", so the Humans left the bots in charge again. It's a trainer: Humans v. Aliens would only be happening at "The Front"; that is, in contested areas where active Alien presence requires direct Human intervention.
Since it's mostly about attacking and using weapons against a fairly dumb bot, you could have various classes, no buildings except spawn points (Nodes or Eggs) and Armouries (Aliens would just evo up), and medbots instead of Medistations. You would only be able to join one contingent in any particular match (Humans vs. Bots or Aliens vs. Bots). Bots could be about as smart as they were in Deus Ex (two kinds: lumbering but strong; quick and deadly). Medbots as usual would be like a dog that won't heel. I know this doesn't help much, because the other places to get Open Source models are the wrong engines (Deus Ex is Unreal and it's not open source, afaik; Stargiege is open source, but different engine). Perhaps some Quake mod somewhere has an appropriate open-source model? Didn't vcxzet/optear already import the Giant Eyeball and Lara Croft model into Trem maps? Giant Eyeball would be the Attacker and Lucy/Lara would be the Defender.
I know. It ain't Alien v. Human. And I can't really help much.
Bot classes:
Medbot - roving medistation
practically same as Deus Ex, you gotta find the health
Defender - slower, powerful (defends "enemy" OM/reactor)
in DX: the big drones; in Q3a: Lucy
Attacker - quicker, deadlier (attacks players, deathmatch-style)
in DX: those little mean buggers; in Q3a: the giant eyeball
Medbot wanders aimlessly heals only Humans (Aliens regenerate)
[Possibly damages Aliens with tesla/reactor attack]
{Yes, much like an Adv Mara, a teammate, I know}
Defender uses more Stage 3 Human weapons (chainguns or lucis)
[Yes I know chaingun is S1, but few can afford to die with one until S3]
{What I mean is slow weapons you move lumberingly in a battlesuit with}
Attacker uses what Ris said, the hitscan stuff (iirc lasgun, rifle, etc.)
[Generally, all of the Light Weapons or Fast Weapons]
{What I mean are all the other stuff except what the Heavies use}
Paint 'em all Human Blue (or make 'em Alien Red in Human v. Bot)
Call 'em Spot (Medi), Heavy (Defbot), Meanie (Perpetrator)
OK, since I can't do any of it, I'll stfu & gtfo.

Thanks. And have a lovely Trem day.

Oops, sorry, edit: Make them all them same size, just like Ris says (yes, I missed it, and I'm too lazy to edit the entire thing). Just armored and powerful for defenders and quick and dangerous for attackers. And hard to find for Medibots. :roll:
Player vs. Bots
not Human vs. Alien
but as Alien you have to destroy a Reactor
and as Human you have to destroy an Overmind
which some bots defend
while others attack you (but maybe your structures, too?)
no builder classes?
teambotmatch/assault/mission/coop-style play only
like a coop SP level
or assault MP map
evade attackers
destroy defenders
accomplish SP/coop mission
default maps & Aegis & the ATCS & UTCS variations (the training maps)
so sorry if that's not what you meant/want/thought/were trying to say
thx agn

yes, i've got nothing better to do right now
