This discussion reminded me of a scene from the movie The Jackal in which an assassin basically mounts a rifle on a three-axis motorized mount, connects a calibrated camera to a mounted scope, and then mounts the thing in a truck/van and parks it near the target and uses it over a laptop w/ wireless connection. I think this was in the 90s and I remember thinking, at the time, video bandwidth and latency would be the biggest obsticle but now days it seems like this setup would be near trivial.

When I just tried to google the scene I saw an ISIS setup of virtually the same thing :/
