Good news for down the road, the XBMC development team has begun to port XBMC to linux. What this means for all of us carpc types is that we will have a cutting edge front end application that does it all pretty much out of the box and is 100% free (OS included). I would encourage all of you to check out the project wiki. If any developers are able to lend a hand please do so.
