flex.messaging.services.messaging.RemoteSubscriptionManager
The RemoteSubscriptionManager monitors subscriptions from other servers, not other clients. One MessageClient instance is used for each remote server. It clientId is the address of the remote server. Using a separate instance of this class keeps the subscriptions of local clients separate from remote clients. @author Jeff Vroom @exclude
