That's pretty much the idea, but not so... huge. :) I'd be most interested
in making a small board, but I need to figure out what the choices are
(obviously). It would have to be safe too.

I'd be using a relay whether doing it on the DC side or the AC side. I'm
not messing with high-power transistors where a relay will do the job just
fine. The HD-PVR is rated at 5V/2A, and I don't want to be messing with
such fun as heatsinks.

As am I (well Electrical, but electronics is a large portion of that).
