there are definite uses for this, but the are so limited, it probably isn't worth while. for instance, i could build a control panel on a pedestal, put the pc inside the pedestal and wirelessly send the video to my ceiling mounted projector, and play mame on my 102" screen. i'd still need to plug the pedestal into the power, but not having to run really long video cables across the floor to my receiver would be cool. but then there is the sound issue.
well, the more i think about it, it still seems kinda dumb
