Dovecot's design issues to consider are as follows:
a) making dovecot support hash/btree/dbm maps for passwd/userdb
   [AFAIR Timo stated it is too complicated to be "cost effective" from
   his perspective]
b) making dovecot support sendmail's "socket map" protocol for checking
   mailbox existence 
   The simple protocol is described in semdmail's doc/op/op.me file
   http://www.sendmail.org/doc/sendmail-current/doc/op/op.pdf
c) making dovecot support LMTP protocol via unix socket
