=> I completely agree with Bob. I don't understand how we 
can rule out the v6only => v4 only communication. 
What do we say to operators who can't get enough
v4 addreses? Deploy a v4 NAT as well as IPv6? 

I can understand that communication between a v4only
host initiating a connection with a v6 only host
is too difficult and probably should not be a priority.
