Oh hell yeah. I'm stopping by radio shack on the way home and making that tonight! I was going to make some kill-switches, but this is a much better idea.
I'm an Electrical Engineer and can make all sorts of stuff. I had been thinking about a radio controlled kill switch. (pretty easy to make). Still a good idea since I'd have the remote to it with me. The problem with the idea - my luck my remote would break at 4 am in bumblephuck.
