IMO lack of really secure DNSSEC support is *the* major blocker. So I disagree
with your comment at the end of section 2.

And I have some personal security concerns about the DNSSEC auto-signing many
sites seem to implement and the security of registry (web) interfaces. I'm
pretty sure attackers will go that route just like they attacked registry
(web) interfaces of X.509-based PKI implementations.

Also I don't like inventing a bunch of DNS RR types for different purposes.

Ciao, Michael.
