This is still much too vague. Is the goal here to turn DNS into
something akin to "Active Directory"? Perhaps a better design is
to use DNS primarily for cross-organizational key management (solving
the "introduction" problem), and to leave more fine-grained security
policy storage to dedicated services such as Kerberos, ... There've
been mutterings of facilitating cross-realm Kerberos via DANE, thus
avoiding the need for manual pairwise shared keys.

I was one of the off-list responders. I still think the scope was
much too broad (not well defined), and that a more narrow definition
would likely suffice, probably just use DANE TLSA to secure the
transport, and do everything else at higher layers (above the DNS).
A requirements draft might be the right starting point, and "aaa"
is much more of a topic for "kitten" than for DANE or DNSOP.
