The reason I've been having a hard time following this discussion is  
that you're using the word "domain" where I've always seen the word  
"horizon" in order to distinguish the concept from the meaning of the  
word "domain" in Domain Name System.

The "gross indecency" here is, apparently, admitting in public that we  
cannot escape the need to amend the DNS standards to recognize, for  
the first time, that we need more than one public horizon, i.e. the  
V4V6COEX public horizon and the IPv6 public horizon.

I do not see how we can escape that problem except by deprecating IPv4- 
only operation.  You want to talk to IPv6 nodes?  Then get yourself an  
IPv6 stack and a default route. Otherwise, have a coke and a smile,  
and shut the frell up.  I'm assuming that rough consensus is still  
leaning away from that, so can we please face up to the reality that  
multiple public DNS horizons are the way out of this?
