Federated model for Satellite

At our company we deploy RHEL in many different network zones and many different locations. It would be good if we could have a federated model for the Satellite server. There would be central (or master) server which would connect to Redhat. This would continue to be the central point to manage subscriptions and update pull down. Downstream servers would pull updates from the central server and support a subset of the overall fleet. These servers would be placed in either corporate LAN, remote sites or DMZs. For DMZs that would be particulate useful as it lowers the surface of attack. For remote sites, it would minimise WAN traffic utilisation.
