Re: [OAUTH-WG] FYI per a request on the last conference call, this is a method for making client registration stateless.

As it says in the draft, this could be used with dynamic registration, manual registration, or any other method of registration. How you get the client_id and the nature of the client_id are orthogonal to each other.

As such, you could easily issue this structured/signed stateless client_id in response to a signed software statement presented during either dynamic registration (which really should be a proper extension of dynamic registration). Alternatively, you can issue this client_id from a manual registration step and then you don't need to do a dynamic registration at the AS at all, since the AS can recognize and validate the contents of the client_id (because it's completely stateless).

I am assuming that this draft fits with the dyn reg draft.  It makes the assumption that every single client is somehow potentially different in terms of registration.  This draft encodes the registration values in the JWT so that stateless registration can be achieved.

Dynamic registration takes a different view from client association, in that dynamic registration has no notion of fixed client software releases that are deployed many times. As such there is no fixed registration profile. Every client is potentially different. In contrast Client Association + Software statements, clients are identified as a particular software and are fixed.

Have I read this correctly?

>From a policy perspective, how would a service provider handle registration of clients that are all potentially different? Why would individual clients need to differ in registration (other than in the tokens negotiated with a particular deployment SP)?
