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.

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