Dear Ron,
They are simply comments on a new draft, nothing more than this. Sorry for making u thinking about Multrans related to these comments.

The call for 
http://datatracker.ietf.org/doc/draft-tsou-mboned-multrans-addr-acquisition/
has ended in May 29th.

It is July 2nd. 
Can the chairs say what the result of this call is?

Tina

It doesn't make sense to complicate the IPv6 addressing scheme in order to support a use-case that will rarely or never be deployed.
