In b81bbd, it was added that using loopback should be possible if
multicast flag was added. However, in config.c, IFF_LOOPBACK flag on
an interface makes it impossible to use a loopback interface.
In fact, I would be very interested to use the loopback. I would like to send local traffic to a multicast address but I have multiple output interfaces. I'd like to be able to bind to loopback and let pimd advertises the multicast endpoint. So I'll try to remove the limitation in config.c instead.
