This may be an expensive option (unless you can do it yourself), but - you could put crown molding in the room - if you find the right crown, it will leave a nice gap btween the wall and the molding. You could then go up the wall, out at the top, run through the molding and then back down through the wall to where you need the cables. It would be a lot of work, but if you're up to doing it yourself you'll only need to go to home depot and get a book on trim, a mitre box, a finishing hammer, a decent handsaw and a tape measure.
You have killed to two birds - you've enhanced the look with a classic trim and it's functional.
I have hardwoods throughout the entire house and know your pain - especially the damn dust bunny hunts I'm constantly on.
Just a thought. Good luck.
