Just to clarify things for myself for understanding this: Today, if receiving UDP unicast, we can use udp://<localip>:<port> to select which local IP address to listen on? But for multicast, we'd do udp://<multicast-ip>:<port>?localaddr=<localip> to select which address to use for joining the group?
