I think that NYSERNet turned up native v6 multicast with Internet2 in 2005, 
and we'd been playing with tunnels since maybe 2003. In all that time, I 
believe we've had two campuses connect to us in order to try it out. And I'd 
be willing to bet that the configuration is broken right now, since I haven't 
touched it in a couple of years.

I started dabbling in multicast so that I could listen to IETF 25 (back when 
there was only enough bandwidth to audiocast), so in a way my original 
adoption of multicast was content-driven.

I also think that the recent examples of C-SPAN during the inauguration and 
the Philadelphia Orchestra's pilot program prove that multicast demand is 
driven by compelling content. We had people lining up to enable multicast so 
that they could see the Philadelphia concerts. On the other hand, the fact 
that there have been two really compelling content examples in the last ~20 
years doesn't say much for our future prospects ;)

Bill.

PS - I just checked v6 multicast with VLC, it's broken. I really should look 
at that config. . .
