when i had to do this i fed 100 from one or two, where the two were HA using non-DNS tech such as NFS or sql mirroring. then i've fed 1000 from each of those hundred, choosing one as primary and one as backup.
if you have a better way, using extant, open technology, to reach 100,000 zxfr/ixfr clients with secure coherent zone content with minimal delay, i'd like to hear more.
when i had to feed hundreds of zones to large populations, i used MZ (see http://family.redbarn.org/~vixie/mz.pdf and perhaps also dotat.at/prog/nsnotifyd/metazone.5.pdf).
if you have a better way, using extant, open technology, to propagate a moderate to large and dynamic catalogue of zones toward a cooperating set of secondary servers, i'd like to hear more.
