Tried out steam's in-home-streaming. It allows you to install a game on your super powerful gaming PC, but play it on your weak little home theater PC while sitting on your couch, or even your laptop, as long as both are connected to the same network and running steam.
It works quite well actually, after I changed a couple settings. Was able to play skyrim and the new devil may cry as if my gaming rig was in my living room. Arkham Origins worked too, but it was just a little choppy, not bad though.
