Clustered durable subscriptions on JBossMessaging

Issue

• We have an application (App-A) with a topic. We also have two remote nodes, which are a clustered set of another app (App-B), and we would like to have both of the App-B nodes be able to subscribe to the Topic on App-A, but only receive the message once between the two nodes.
• Is this where clustered durable subscriptions come in? If so can you provide an example or link to documentation on how to make multiple subscribers connect as one?
