Winsock (or least, the MS implementation) doesn't allow this. I didn't know
that recent BSD variants have this capability - thanks for the correction.
To answer your question - yes, the bind() of a multicast address should
automatically join the group. So this is another reason to make
sin6_scope_id field be an interface id for multicast addresses of all
scopes.
