There's your reason not to right here. It takes quite a bit of effort to send
information on the power lines. The bottom line is when you don't have drywall
up, dropping conduit/cable in the wall is the most efficient thing to do.

I'd advise putting in conduit (1 inch PVC would be wonderful). Then you can cut
out panels in the wall wherever you like. Be sure to put a string in the
conduits so that you can draw write through it. It's absolutely the most
flexible option...
