I have tried using the spare pairs for remote shutoff. I can't see any
reason why this should not work with RS232, but USB2 has max length of
5m between hubs (USB 1 less I believe).
A simple way to do this would be to buy a pair of cable extenders and
modify those.
Don't forget to label it up though :)
