I've had a brief skim.

It's entirely driven by zone confidentiality, which is a fine thing, but
from my point of view the interesting possibility is to get transport
integrity (like TSIG) but with much simpler key management.

Single-ended public key authentication of the primary with IP-based
access control for secondaries should be an easy upgrade that do not
currently use TSIG, and really nice for stealth secondaries.

Double-ended public key auth will help reduce the need to break out gpg
for key exchange with oldskool third-party secondarying arrangements.

So I think this is interesting from the dnsop perspective as well as
dprive.

Tony.
