Looks good to me. Pleased to see this is being spec’d out. Do you think it would make it into Pike?

This is going to be an item at the upcoming PTG since it seems like something that's bigger than nova or cinder and will need to be dealt with by the broader community to get it right, i.e. maybe the Arch WG needs to help out here?

Completely agreed. The problem of both the delegated permissions and quota needs a consistent implementation semantics across projects. Since this functionality will be delegated to a resource co-ordinator who may not have the same level of OpenStack knowledge as an admin, keeping the learning curve for this role as low as possible would be a worthwhile goal.
