In regards to the cluster ... we will be having 2 different clusters .. one of them will be a backup just in case the primary cluster goes down ...we wanted to check if federation can be used to sync up these two different env's on a WAN on just few queues...

You can buy commercial support for RabbitMQ, either for the MPL licensed
version or the vFabric packaged version under the VMware EULA:
http://www.vmware.com/uk/download/eula/universal_eula.html
In this case you also get entitlement to the JMS client.

If you have further questions please send to support at rabbitmq.com

You should avoid clusters that span unreliable networks. See

You can define a high-availability policy that causes only a subset of
queues to be mirrored. For details see
