Sounds kind of like GData workflow, is that what you are going for? Source application installation must connect to registered API application though an application authentication URL. API application author has full control over expiring any application tokens at any given point causing all source applications to have to reconnect.
So in my mind, to simplify things, I see two levels of authentication. First the source application must be authenticated before it can be used (key). Then once the source application is ready, it can be used for to authenticate specific users' accounts once allowed by the user (token). Does this also mean it requires more levels of checking on the logic side? First check the if keys have expired, then check if tokens have expired? As a fan of the GData workflow, I think this sounds very good, but I would still love see a request/response oriented workflow example.
