 So is what you are really saying is that the addresses "may" wind up in
the DFZ and you do want them to be able to transit the DFZ?

otherwise anywhere your ULA packets live the processing entity should
also be able to reach the ULA-DNS .. 

what I am hearing is that you feel if it is technically possible to
route ULA across the DFZ then we should not limit that capability..
leave it up to the user..  

I'm still confused..
