Dear Steve,

what you document is that everyone can mitigate a removal of a TLD 
from the root. I suppose there is no intrinsic difference with 
mitigating the removal of all the TLDs, i.e. the removal of the root? 
This means there are two strategies that can be followed 
(alternatively or in parallel):

- to be ready to mitigate
- or/and to install a permanent mitigating solution under the form of 
an homeroot experimentation.

You explain that "root zone entries have a 48 hour time-to-live 
(TTL), which means it will take two days before all of the caches 
around the world are drained of the old entry.  Put a another way, 
the impact would be about 2% per hour." This means that a daily run 
of the projected EZOP application is enough to keep an HomeRoot in 
tune with the top zone reality?

Do you have some figures on what EZOP wants to report in addition to 
the root file, i.e. the number of name servers declared via the TLD 
zone files which are not listed in the root file (I do not know how 
one calls them)?

Thank you for your inputs.
