Could you also give us a little more information about your use case. It seems that you want to have two independent messaging servers. Why? Usually a client app sticks a message on JBM, and another client app reads the message. As gaohoward said, you can cluster JBM, but then it is more of a single logical instance spread out among multiple hosts.
