Have you ever actually been involved with really large scale multicast implementations? I take it that's a no.
Nope. I prefer small scale. :)
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.
So we don't use multicast, fallback to unicast deployments on the Internet today for various events/streams?
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.
Clients can't fallback to unicast when multicast isn't functional? I'd expect multicast to save some bandwidth, not all of it.

Cool. I did a 3 seat multicast video network, and honestly am largely ignorant of multicast over the Internet (on my list!) but do listen to people discuss it. :P
