Interdomain IPv6 multicast has existed for years, but has actually decreased 
in adoption as unicast IPv6 has grown. Stig Venaas did a hands-on workshop at 
a Joint Techs meeting in 2006, and at that point it was fully deployable. Not 
necessarily *usable* thanks to arguments about who owned the patents to do 
MLDv2 and various other implementation issues, but deployable on the 
backbones.

I don't actually know when we put it on the NYSERNet network, probably in the 
early 00's.  It might still work, I have no idea.

I also haven't looked at the mix of OS/application/router support for v6 
multicast in a while. A quick glance at the VLC page says that it supports 
MLDv2, but doesn't break that down by OS. I think embedded-RP has been in all 
the routers for a long time, which is good. 

If someone really wants to try this stuff out, I can stand up VLC sources 
(probably) on a working network (maybe)...
