That's a very good idea.  The CURL support in GPG is fairly generic,
so it should indeed work.  We would just need to add "dns" to the list
of protocols that GPG passes to gpgkeys_curl.  CURL would take care of
the rest.

LDAP-via-CURL would work as well for getting keys, but LDAP is
somewhat special where OpenPGP is concerned.  CURL supports fetching a
LDAP URI (a la RFC 2255), but gpgkeys_ldap does a few more things like
sending keys to the keyserver, searching for keys, etc.
