But you're talking about a case where glue is required. I'm talking  
about the case when glue is not required.

I can add a host object for NS.EXAMPLE.ORG in the INFO registry with  
no address, which is sufficient for me to link ORG domains to the  
NS.EXAMPLE.ORG host.

My point is that if glue is not required, and host registration can be  
done without specifying an address, then any registrar will do and  
they do not need any special "v6 readiness".
