Satellite connections are pretty useless for anything real-time from/to the Internet. The packet latency will be at least 1 second up to 3 seconds.
In a real-time game, such as AH, what you see on your computer will be at least 1 second behind what everyone else sees. And when they see you they are seeing you 1 second from your real position on your computer.
Everything can look smooth as silk on your end, but your are still running at least 1 second behind everyone else.
56K dial-up would be significantly better for any real-time activities.
