Now that MIME is out as a proposal for mail, I still believe that these problems should be addressed before MIME is appropriate for database, archival and retrieval applications. In addition, the current mechanism in MIME for external references suffers the same problem that other references mechanisms that are based on hostname/pathname have: files move, change in place, host names come and go over the years. Both these problems are not trival to solve, but I don't think they are unsolvable.
