and you have a giant confluence of number resource management and
operational practices here  as well.

For roots? TLD? ccTLD? (is there a potential difference between the
TLD types?)  Is diversity in numbers of networks and numbers of
locations per entity good enough? (.iq served out of US, Iraq, AMS on
3 different netblocks by 3 different operators ideally serviced by a
central controlling gov't entity... wait .iq changed... use .co as the

Is, for lack of a quicker example: .iq 'good' or could they improve by
 shifting their NS hosts to blocks outside the /16 or
does it matter at all because they have each announced as a /24 with
no covering route?? (so if someone fudged a /24 max prefix length
filter to /23 they'd be broken either way?)

Some of this is covered in rfc2182 anyway, right?
