I would consider running HDMI cable from my media closet to alot of the rooms. Its amazing what you can do with HDMI Splitters / Matrices and a 100 ft. of HDMI cable. The ability to use you PS3, XBox, Media PC, etc in other rooms is huge. My Bluetooth keyboard, the bluetooth PS3 remotes, and the XBox remotes all work through the walls and at a decent distance. Plus radio frequency remotes are becoming more common. Just something to consider.
