At this point, the process for maintaining synchronization of authorization rules in a distributed environment is not in the scope of this draft. It seems like a general topic beyond subscriptions. That said, it would be great if a publisher subscribed the authorization rules on the centralized server -> this would result in a push of permission changes as they occur :-).
