[multrans] Clarification question about Problem Statement and Use Cases draft

[Maglione Roberta <[e-mail]>]

Hello,
   I have a question about the prioritization of the scenarios described in draft draft-jaclee-behave-v4v6-mcast-ps:
Section 3.2 "IPv6 Receiver and Source Connected to an IPv4-Only Network" says that 6-4-6 scenario according to the BEHAVE WG  is of lower priority, I would like to better understand why.

In my opinion "IPv6 Receiver and Source Connected to an IPv4-Only Network" use case could also cover the scenario where both receivers and source are IPv6 and they get IPv6 unicast connectivity from an IPv4 network by using 6PE solution (for unicast traffic).
If I am not wrong this use case does not belong to behave discussion, but I believe that having a multicast equivalent solution for 6PE may be useful for a Service Provider that would like to start offering IPv6 multicast keeping his own backbone network in IPv4.

I would appreciate your comments.
Thanks,
Best regards,
Roberta
