In very simplistic terms, that is _exactly_ what we are building. Only
in our world the "directory" server is actually the mail server for the
recipient, which hosts the "signet." It makes sense that if the mail
server is offline, then you can't deliver mail anyways, so why introduce
an external piece to the puzzle.
All the extra complexity is either to prevent MitM, or optional.
P.S. DIME requires TLS v1.2 using the ECHDE-RSA-AES-256-GCM-SHA384
(OpenSSL name, I don't know the RFC name by heart). So yes, TLS is
required for a "conforming" DMTP server.
