RFC 1437          MIME Content-Types for a New Medium       1 April 1993


   The following is a message that gives a somewhat simplified rendition
   of a well-known American politician, starting from the top:

   From:  "Nathaniel S. Borenstein" [email protected]>
   To: Mark Linimon [email protected]>
   Subject: Think hard before reconstructing
   Content-description:  Dan Quayle, low-res version
   Content-type: matter-transport/sentient-life-form
           height = 200; width = 60; depth=60; resolution=100000

   Obviously, a real politician's skull is more complex than pure iron,
   as is its interior, but this simplified example should give the
   general flavor of the protocol.

   (A caveat, however, in the reconstitution of Vice-Presidents of the
   United States: allegedly, some of the matter-reconstitution schemes
   currently under development are reputed to perform less than
   optimally while trying to reconstitute areas of relatively high
   vacuum; for instance, their skulls.  A recommended acceptance test
   might be to experiment with subjects whose skulls are only at partial
   vacuum, such as Vice-Presidents of Marketing.)

MHS (X.400) Gateway Considerations

   The proper behavior of a MIME/MHS gateway with regard to the
   transmission of complex multimedia messages is a topic of ongoing
   investigation under the auspices of the IETF.  The addition of matter
   transport should not significantly complicate that effort, as it is
   already necessary to specify gateway behavior for MIME types that
   have no X.400 equivalents, and matter transport is simply another
