The problem is one of network latency. This has been a major hurdle for
games like Aces High, Air Warrior and WWII Online. The server should
handle the collision to avoid situations where the shooter client sees a
hit and the shootee client doesn't.
Multi-player air combat can get pretty complex if you plan to support more
than a few clients at a time. Network latency can be a huge problem,
especially if there are modem based clients. You're going to have to come
up with a special protocol to handle it as the "Standard" (milspec)
protocol is far too verbose unless you're on a local LAN or high-capacity
WAN. A lot of time and effor has gone into this area of online gaming,
but I don't know if the research that has been done is on the net. I'm
sure there are a few places on the net that explain the ins and outs of
this kind of thing far better than I can.
