Exposing it via a standard method, like LDAP, would be awesome, and I agree entirely unlikely considering the (passive aggressive?) stance Facebook and Google are taking on exposing that information. Exposing your address book via a method that allows you to consume it programatically and thereby make it more useful? We wouldn't want to enable competitors because we obviously can't continue to exist or be relevant using any method other than locking people in.
