Does anyone know if it is possible to run JBoss as a cluster using only unicast, no multicast?

More importantly, does anyone have experience actually getting this to work?

The unicast should be doable using a GossipRouter (as referenced in the JGroups Manual - see sections 5.3.1 and 5.3.2).

In our cluster, we use TCP multicast for the production instance. However, our unit tests for our JBoss Cache listeners require a pseudo-clustered environment, and we use a GossipRouter instance to successfully create a transient cluster that lives for the life of the unit tests and allows successful cluster communication.
