If you want to deploy native IPv6 multicast in your network, that's your
prerogative. I am not looking at limiting other peoples' choice, I just 
want ability to choose the functionality I feel is important for me (and 
for others in the end).

Of course multicast over tunnels works, it's just that normally a tunnel 
is terminated fairly centrally in the network, and replicating 10-20 meg 
HDTV streams doesn't really scale in that topology. You want the 
replication to happen as close to the customer as possible (DSLAM, 
ethernet switch etc). I see TV as the main driver for multicast, and doing 
that over tunnels is just not feasable to me.
