That's just so ridiculously easy, it should be highlighted by twitter. They're a bit distracted I guess with their meteoric growth to market this properly.
Specifically, all that would need to happen to make this perfect is for OAuth requests for a user that already have an access token automatically push through to the callback phase instead of requiring a "re-allow" of the client's services. This wouldn't conflict with the OAuth spec in any way that I'm aware of.
