Scott Instead of thinking one must choose between a locally consumed registry and a lookup service, why not both? In the land of DNSOP we put out RFC7706 which talks about running a copy of the root Nameservers locally to speed lookups. This seems to be so highly useful that we're just finished WGLC on 7706-bis. So we could decide on doing a combinatory of #3 and #1, with the right mechanisms. Just a thought.
