1. The fragmented name space is a reality and has been for some time (dns split horizon search on google reveals 500k pages)
2. If endpoints use proper globally registered DNS names they will be able to communicate. If they use something else the behaviour is undefined.
I think there is more value in thinking about how we can integrate local and global naming than in trying to protect people by not allowing something to not be registered in the global name space.

I don't think the DNS t-shirt looks better.

I do recognise them. The data that we have shows that they exists. I just think that it is nothing the IETF should invest time in. While the IETF cost is significant lower than the ICANN cost I doubt that RFCs will get lawyers out of ICANNs back. I think the ship has sailed and it now is a political (layer 9) problem who can register what in the global DNS name space.

So long
