Its tought to prove a negative. I'm extremely confident the answer is yes, public internet multicast is not viable. I did all the google searches, check all the usual CAIDA and ISP sites. IP Multicast is used on private enterprise networks, and some ISPs use it for some closed services. I got sent back with a random comment from a senior official saying "but I heard different." I bit my tongue, and said I would double (now quadruple) check. If any ISPs have working IP source-routed multicast on the public Internet that I missed, or what I got wrong. That's what content distribution networks (cdn's) are for instead.
Hi Sean, I'm sure that transit providers with whom you have no commercial relationship are happy to let you program their routers to forward your multicast packets. Not just happy, ecstatic I'd say.
