what's new? how about the operational technical effects, like data from modeling various resolvers' responses to a large root zone?
Yep. That is an area that has been identified as needing additional study (see comments by kc, summarized in http://www.icann.org/en/topics/new-gtlds/summary-analysis-root-zone-scaling-...).
Things can get hairy with high update rates, so I'd encourage ICANN to dig in its heels about the 2x per day update rate
I don't know anyone who is pushing to increase the update rate of the root zone.
An interesting question is what the load effects will be on the root.
One of the studies relevant to this was done by DNS-OARC. See http://www.icann.org/en/topics/ssr/root-zone-augementation-analysis-17sep09-.... There was an intent to do some follow-on studies, but from ICANN's perspective the interesting scaling questions turned out to be related to the provisioning side, so focus moved away from impact on the root servers.
