Have you ever actually been involved with really large scale multicast
implementations? I take it that's a no.
The -only- way that would work internet wide, and it defeats the purpose,
is if your client side created a tunnel back to your multicast source
network. Which would mean you're carrying your multicast data over
anycast.
If you, the multicast broadcaster, dont have extensive control of the
-entire- end to end IP network, it will be significantly broken
significant amounts of the time.
