Guys there seems to be a bit of missinformation about what is the BOS/M/K server capable.
I can't speak from mission designer point of view but I can tell you what I observed on the servers.
There is a possibility to lock loadouts. You can lock modification use and bomb loads. Its usualy used to lock the 2500kg bombs on Heinkel and 1800kg bomb for Stuka as they are overkill for most small targets. Or to lock bombs for FW and BF when they want to force bomber usage.
Death kick is not possible (AFAIK) but you can force a death pennalty wait period. Set it to 2 hours and you have the same thing.
A kick is possible with some third party tools. On some servers are checks if your squadron or pilot has the supply points or aircraft to fly your choosen machine, if not, you are kicked when you try to take off. The same with sides. If you are registered LW you can't take off with VVS aircraft.
You can force a side switch wait period. So if you pick the wrong side, you are forced to wait until you can fly again if you switch sides, and so you are probably out of fight.
Those wait periods can't be fooled by disco and reconnect. He remembers.
This is a BOS feature, no tool necesary.
Some kind of object tracking is certainly possible. There are dynamicly changing front lines durring mission and aditional targets are activated after the destruction of primary targets or a number of targets. The front line can move in both directions, its not a prescripted move that can't be undone.
Airbase can change owner in middle of a mission even several times when the front line moves.
Aircraft can be made available durring missions and modifications can be unlocked during mission.
I think Baron would mayby fill some more options that I dont remember.
