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

    http://datatracker.ietf.org/doc/draft-ietf-mboned-auto-multicast/

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

    http://datatracker.ietf.org/doc/draft-ietf-mboned-v4v6-mcast-ps/

Thanks for your attention. Privacy will be respected if people want to reply privately.
