Usage of BIND in TLDs

I know.  I've been watching his foray into the world of PowerDNS.  I don't know 
whether he decided to try it before or after he read what I posted.  (What's 
particulary interesting is that he's trying to configure it to do *exactly* 
what I said, last year, a TLD registry, such as Verisign, could do to thwart 
the flawed "delegation-only" mechanism.  I am waiting to see whether he achieves 
it.)

BC> ( Note that a given nameserver may serve multiple TLDs, [...] )

So a breakdown by number of distinct server IP addresses (not server 
names), in addition to the one by number of TLDs, might be a good idea.
