Microslop just announced the overview of a program where you can digitize your physical collection. Just shitting in the wind here, but I have heard that, for a while now, Xbox discs have had unique identifiers. So, they'll take that disc license and lock it to your account so you can play your disc games digitally without need for the disc in the drive. Whether it downloads the data or installs from the disc, I don't know. Plans also state sharing will be included where you send the license(?) to a friend. Details are vague at the moment.
