Re: multiple clusters on a single multicast IP?

I would not recommend it. Although the multicast traffic per cluster is
defined based on clustername and multicast address and port, and Jxta
has the capability to route the messaging to the right members, it does
impose the overhead of having to discard messages meant for the other
cluster received on one cluster.

It is preferable to use a different address and/or port combo.
