You'll be able to link other Xbox Live accounts as having shared access to your library when you first set up a system and will also be able to add them later on (though specific details of how you manage these relationships is still not being discussed). The only limitation, it seems, is that only one person can be playing the shared copy of a single game at any given time. All in all, this does sound like a pretty convenient feature that's more workable than simply passing discs around amongst friends who are actually in your area.
