Network of Embedded Brokers

I would like to setup a network of embedded brokers. Each broker would be
running in an instance of tomcat on a separate server. Each tomcat instance
would also have a single producer and a single consumer. The producer should
publish to the internal broker. The consumers should receive messages from
each of the other brokers, but not its own.

So far I have managed to get a single instance working except for that fact
that it consumes its own messages, which I would like to avoid. I don't know
if a configuration like this is even possible. So if anyone has something
configured like this I would really like to share notes and configuration
files.

Thanks,
Pete

Yes, I am talking about topics. This looks exactly like what I was looking
for. Thanks very much. Now I just need to get the brokers communicating and
I will be golden.

Hello Pete,

are you talking about TopicPublishers and -Consumers or about Queues?
At least in the case of Topics there is a solution to your problem: 
Create your TopicSubscriber with the parameter noLocal=true.

ActiveMQTopicSession.createSubscriber(Topic topic,
                                         String messageSelector,
                                         boolean noLocal)
http://incubator.apache.org/activemq/maven/activemq-core/apidocs/org/apache/activemq/ActiveMQTopicSession.html#createSubscriber(javax.jms.Topic,%20java.lang.String,%20boolean)
