IPTV, Multicast, and IPv6 Transition

This may be way off in the future for some of you, or others may be past 
it. In support of possible work on IPv6 transition in the IETF MBONED 
Working Group, I'm looking for an indication of what use cases are 
realistic for operators who:

-- deliver IPTV to their customers
-- use multicast for the purpose, either now or in the near future
-- are making the transition from IPv4 to IPv6.

First question: does anyone anticipate a situation where you will have 
to translate multicast content from a IPv4-only source so it can be 
delivered to an IPv6-only receiver, or vice versa?

Second question: the current official view is that dual stack is the 
sensible way to transition your network, and failing that, you can use 
Automatic Multicast Tunneling, an almost-ready Internet Draft available at


to tunnel multicast packets through a single-stack network when 
necessary. Do you consider your requirements adequately addressed by 
this view?

People who really want to be helpful can comment on the problem 
statement and use cases documented in
