I have worked with the folks at Precision Remotes since 2002 and their products could NOT be used for hunting over the internet. You can control all of the motion and optics via RS-232 interface, so you could point it, zoom the cameras, etc. over the internet if you had their software. However, the fire control circuits are on a different circuit board and NOT accessible from the RS-232. Only a live operator with the dedicated remote interface directly connected could enable and fire the weapon.
A company called Foster Miller took the Precision Remotes gun chassis and put it on their Talon robot for the military. That system (called SWORDS, the new version called MAARS) was wireless remote operable and Foster Miller enabled the weapon to be armed and fired from the secure wireless controller, but still not "internet" controlled.
I agree that "internet hunting" has no future, but light weight, man-portable remote weapon systems do have a legitimate purpose for the police and military users.
