I'm right with ya funked. Things could be improved from the current regime of pkills exploding and abandoned planes disappearing. Take care of these first, then we'll start asking for dead tanks to leave smoking hulks for five minutes.
Ack tracers/flak are client-side. Basically, if your FE detects an enemy plane (such as your own) in range of a functional AA emplacement, it shows tracers.
My understanding of "tracers on login" phenomenon is:
You come into the arena, and you are assigned a position (the lowest numbered airfield on your side). You sit in the tower, and the host streams UDP packets at you containing information on all the planes near you.
Meanwhile, TCP packets are sent to you concerning the arena setup: (probly clouds and wind at start, as well as basic settings), Ownership and status of airfields, ownership of strat targets, the roster (name, squad, country, plane type), and (finally) damage status of all objects in the arena.
The ack firing at friendlies is because your FE is receiving packets for a player whose roster info has not been received. Therefore, it is assigned country 1 (bishops) and plane 1 (p51). When this gets cleaned up sometimes the acks don't stop shooting. Of course, what I've said above is entirely conjecture and without doubt contains errors (for example are those "enemies" always p51s?)
I think ack hits are done by the host.
