i think you can avoid this if you make your MIME document descriptor
in the following way.
1- an ascii part containing an abstract for the document and
describing all the document representations (size, real format...)
2- for each representation an external-body ftp part

then the mime document itself is very short and after you read
the ascii part you can decide to transfer( or not )
only the representation that you want
