A linux channel would be a remarkable accomplishment... if you can run linux on it, you can pretty much run anything.. develop games that takes advantage of the wiimote, media player... divx/xvid playback -or whatever codec you want to use... xboxmedia center can be ported over and access to the SD/USB ports =) External hard drive?
This is all gonna take time though, I don't see anything else major now for atleast 6 months. So i'm gonna try and not get excited yet.
