among cooperating wizards, i think this has a real benefit over its costs.
but for the rest of the world, we'll keep adding anycast root server nodes
to serve the same purpose but without the end user wizardry. (and even if
kato did it first and ohta talked about it first, *i* heard about root server
anycast from david conrad, and i started doing it in f-root on that basis.)

i remain perplexed about the general perception that AXFR is bad for a root
name server. it's not. RFC1035 describes some resource management techniques
for TCP state blobs, which the root servers follow. the chance that an AXFR
will be blown away by a TCP query is very high, and so, it's bad for clients
to make production use of AXFR from busy servers. some kind of AXFR-only
service seems indicated. we could put one up on 18.104.22.168 in a few days if
IANA asked for it. (that's F+1 as IP addresses go.)

i've long ranted about this myself. perhaps if IANA had a mailing list where
the topic of root name service could be publically and openly discussed, all
the existing rootops (and hundreds of other people) would join it? or are we
doing ok now that there's this (dns-operations@) mailing list to use for that?
