Waaaaay back in 2002, a little project known as Xbox Media Center (XBMC) was developed by a group of open source coders. XBMC ran unsigned on the original Xbox via either a hardware modchip or as a software exploit and replaced the traditional Xbox Dashboard with a media-focused interface. There’s been a Linux version in development since early last year and there’s now a version being developed for OS X.
The Mac project is being led by Elan Feingold, who’s just recently been interviewed by 9 to 5 Mac. It’s an interesting read and this version of XBMC looks to be a pretty promising use of an Intel-based Mac Mini, if you’re so inclined.
