Getting back to my original discussion with Barrett, what should we do
about naming? I initially though that segregating v6 in a subdomain
was a good idea, but if this is truly a migration, v4 should be the
interface segregated.

 I have also read Jordi? saying that no dual naming should occur, but
I think this is unrealistic. (Sorry if I misquoted you, Jordi)

We are. There are an unending supply of small details that are in the
way at the moment. :-)
