> ${jboss.messaging.datachanneludpaddress, jboss.partition.udpGroup:228.6.6.6}
> this would allow users to set the udp group on the command line when starting jboss.  What it would do is put the datachannel and the control channel on the same udp address as everything else, but they would have a different port.  This would enable users to segment their clusters easier just by changing the udp address on the command line.  So we'd still keep the old variable to be backwards compatible.  We would add the new variable and leave the default as it is.
> Right now we tell customers to set the -u to isolate a cluster.  But now in 4.3, we have to tell them also to change the jbm information.  This leads to inadvertant cluster formations with JBM, when the rest of the machine is not in a cluster at all.
> We of course would want to change the control channel udp address also.
