It would probably be better to build it at the switch level. I would think there would be a change in resistance when there is ANYTHING added/removed from the cabling that could be measured by the switch. You could then have it disable that segment upon such detection if you'd like.

I bet some security conscious folks will pay lots of $$$ for that.
