well...after a bunch of looking and weighing pros/cons, i just decided to be a little handy with the trimming around the walls, and go with running cable.
i was able to run a thinner cable through the area behind the trim, and replace without any noticeable gapping/etc.
it'd be nice to cost-effectively wirelessly connect, but it just really isn't. i don't want to spend $50+ on another piece of hardware that's not really necessary - so, with a little ingenuity and a short afternoon this option worked well for my needs.
thanks for the ideas!
