MechInstaller released! The MechInstaller is basically a combination of the MechAssault savegame exploit and the font loader dashboard exploit. Its whole purpose is to provide an easy way for everyone to permanently install Linux on their unmodded Xbox and at the same time it allows normal Xbox usage.

so basically, you install linux on your unmodded xbox allowing you to use it as normal pc to play movies, mp3's etc and still use it as normal xbox.
it should also allow you to play downloadable backups *cough* of games on a unmodded xbox
