Yes, you are right it doesn't follow AF_UNIX semantics so Unix sockets is not the best place to add our multicast implementation.
So, now we are trying a different approach. To create a new address family AF_MCAST. That way we can have more control over the semantics of the socket interface for that family.
We expect to have some patches in a few days and we will resend.
Does this makes more sense to you?
Best regards, Javier
