I believe this group is interested to taking care of the details
so that this concept will be implemented in a consisted way. 
While the scope of the IETF work may simply be MIME definitions
and the IPP protocol, my suggestion from a couple of weeks 
ago to develop a scenarios document that delt with the details
of a complete implementation still stands.  We can product all
the RFCs we want but if we don't discuss and document the
details, we are doomed to a paper standard and a commercial
