This might be a little off subject, but from what cryptic information I've gathered from the few releases I've read, it sounds like you may have to have a game registered to your online account to play it. Meaning, you can't lend games to friends, rent from Gamefly, etc.
If that's true (which I doubt will get through in the end), and they'd let DRM stomp on their own customers, I don't hold out much hope for their future indie support.
