I've got an Xbox softmodded to run XBMC- it's pretty much the centre of my living room experience. It was only moddable by using one of the Mechcommander discs that allowed a similar Linux hack to the one described here.

So come pay day it might well be time for me to pick up a copy of Zelda for safe keeping, till Wii homebrew progresses... my Wii, a USB hard disk and XBMC would be an incredible little living room addition..
