Would be pretty cool once usrar support is in. You could just dump all your rars/zips into MXM\Installs or something, and have a menu item to install apps. Then the script can search for rar/zip files in that folder, and install the app automatically, or let the user specify a directory. Maybe this could be integrated into the file manager.

Good for FXP'ing straight into the xbox.

And with the new SETFUNC MD5 you could have it verify that any new apps are infact different than what's already on your Xbox (if you already have that app)
