Fair enough.

I would prefer CreateClientAssociation and CreateManagerRegistration (to keep with our current terminology) or just CreateAssociation and CreateRegistration since these are not service-specific. On the Client side I would expect that association will provide access to all services "shared" (registered) through the Cloud via the service endpoint provided in the response.

On the Cloud Print Manager side I would expect the manager to provide the service (or list of services) it wants to register along with any descriptive information - initially we are just talking about Print, but why have/force separate Create<service>Registration operations for the common MFD use case? Again, following the subscription interface we have in IPP, you can (today) create multiple subscriptions with a single operation and the response contains the corresponding list of subscription IDs - we'd use URIs for the Cloud Print Services.

Unless you ask for "forever" and the service allows it... :) IPP Notifications already support this use case...
