Remoting 3 is architectually fundamentally different from previous versions. Connections are designed to be long-lived and shared and multiplexed with many protocols across one connection; in addition the API structure is substantially different. Remoting 3 acts in terms of Endpoints. You create an endpoint, register any local services on it, use it to establish authenticated connections to remote endpoints or to create servers for incoming remote connections. You then can use connections to open clients for specific services (for example, EJB, JNDI, and JMX are all separate services in JBoss AS 7 but you can access them all over one connection).
Thus your question doesn't really have meaning in the context of Remoting 3. Hopefully I'll have some time sometime soon to start developing and publishing some good documentation.
