Thanks, but I seem to remember a message indicating that the RFC's
"expired" and the multicast addresses have been re-purposed. I'm not
sure about that though - it may have occurred in a [bad] dream.

However, your earlier point about public routers forwarding multicast
datagrams is well taken, so I don't think multicast will work for the
joe-beer-drinker or mom-and-pop crowd (which seem to be the main
audience for these webcams).
