Electro: It's not even possible to do the in-air turning stuff you can do in Quake on bots, since they don't have that weird client bug which causes the extra directional speed you gain from slowly turning in mid-air. It comes from mouse movement interpretation, and bots currently don't have fake mouse input, you set their angles directly in the code. Even if fake mouse input was implemented, I'm very unsure it'd still be possible, since it runs on the server, and would most likely be treated very differently.
You
could obviously do it by adding specific code for this kind of behaviour on bots, that they get more forward momentum if in-air and their view-angles change at a steady speed in a particular direction. But ehh... yes...
You should just do jump-test predictions with STW or something similar, and stopping in mid-air wouldn't be hard to do either if you just find a use for it, and define where it's used. The latter is the hard part, but not even nearly as impossible as the turning stuff. You could just tracebox down until trace_endpos is where you want it to be, and make the bot do input in the reverse direction of his current velocity.
Just my two cents. I'd just really like you to get this out and playable, rather than get stuck on something no-one's ever considered sane
