A delivery layer is included having a content store in the intermediate domain for storing content from content providers in the at least one content provider domain for delivery to a consumer. A discovery layer has a content metadata store in the intermediate domain for storing metadata associated with content available from the content store and from content providers in the at least one content provider domain. A support and service layer administers the delivery of content from the content store, and from content providers in the at least one content provider domain, to a consumer using metadata stored in the content metadata store.
