A really nice and helpful document.

A suggestion:

It should discuss RFC 4470 Minimally Covering NSEC Records, and the
related idea of NSEC3 "white lies" implemented by Dan Kaminsky's
Phreebird. (I can't immediately find a good description of how the latter
works.) Both these require on-demand synthesizing and signing of negative
responses, whereas the mechanisms that Miek's draft currently covers are
all designed for serving from a pre-signed zone file without requiring
online private keys.

Tony.
