I meant that the random selection idea would select the port for a cluster of nodes, not just a particular node, but it would have to exist at a "cluster" startup level not a "node" startup level.
If I utilized ${system property name} replacement in the file, and then passed the same port for a multicast configuration to the VM as a system property for every node in the cluster, it seems to me it would work. Currently, we are doing that for the cluster partition name, but you are right, I have include that substitution in several different places. The port number would be a single substitution in a single file. Does the cited example in UDP.java easily map to multicast configurations too, so I could test random or hash-selected cluster multicast port numbers for listeners?
