Well, JGroups needs the bind address, as this forms the address of a member. However, if we only used the bind_addr to determine the local_addr and used no bind_addr for the datagram socket creation, the OS would *not* pick an interface, but instead use the wild card interface 0.0.0.0, so packets would get received over any interface if the port matches.
This is doable, but wouldn't help us with the issue at hand.
