        Actually, that's one of the things I wanted to look into. I'm not
sure if there's a path through here with (even non-linklocal) multicasts
that end up without an interface set. And I'd to do some testing of
different cases to see if they behave as expected; also compare to the
similar sendmsg() cases.

        Good, thanks. It has been this way for years now, and I'm out
too. :-) Enjoy,

                                                                +-DLS
