One of the uses for an XP intermediary discussed in [1] is to act as an
inter-transport router (e.g. SMTP<-->HTTP). In this case the same
intermediary (or one with an equivalent inverse function) would need to be 
interposed for both request and response.

A further question relates to the ordering of intermediaries: is it 
reversed for responses ? i.e. if we have three intermediaries A, B and C and
the request path is ->A->B->C->, is the response path ->C->B->A ?
