        Not particularly new. This was/is the promise of DNSSEC.
        early work, the TBDS and FMESHD projects.  Current IETF
        work, OE and IPSECKEY.

        Not entirely.  The reverse maps are a well defined infrastructure
        space.

        There are some other problems w/ using the DNS.
                No revolkation process.
                DNS caching
                third-party trust (DNS admins != delegation holder)
