	Yes, but can you also load a copy of every other ccTLD that is 
within Europe?  All of Poland?  Germany?  All the other countries? 
All their in-addr.arpa zones?  What would happen if you had to load 
ten times as much information?


	At the time I was doing my research in 2002, the largest zone I 
could get a copy of was .tv (over 460,000 records).  At that time, 
.cz was about 387,000 records, .hu was about 299,000 records, .pl was 
about 291,000 records, and .se was about 290,000 records.

	What are these numbers today?  How many records are there across 
all the ccTLDs that comprise the countries which are in the EU?  How 
many records are there for Turkey?  Now, what about all their 
respective in-addr.arpa zones?

	How much memory would be required to load all these zones onto a 
single NSD server?  Could you still handle it if the requirements 
jumped by a factor of ten?

	Are the operating systems ready to support those kinds of memory 
requirements?


	I think that's the scale of problem that is facing us with a flat 
.eu zone, and far more rapidly than anyone here is giving credit.
