Maybe we need to propagate some other kind of machine id in the state too? Or we propagate a list of NICs per box in the state.)

This is quite easy to handle due to the java.net.NetworkInterface.getNetworkInterfaces() method, from which all addresses on the machine can be discovered.  The  o.j.cache.buddyreplication.NextMemberBuddyLocator.isColocated() method uses this.
