I can't answer your specific question, but just want to suggest that you read over the JBoss Remoting documentation, as that is what JBoss Messaging uses for communications. The default mechanism is a callback scheme where the server has to initiate connections back to a client for the client to "receive" messages. It sounds like you'll have to somehow configure Messaging so that it can distinguish between a client on the same box and itself?
