This really came out of the description of the original problem.  A 
request/response conversations was initiated and the initiator crashed 
before receiving the response.  The replay of a message at this level, 
especially as we are using WS-Addressing, would surely become the domain 
of a reliable transport.  My suggestion was therefore to defer this to 
the transport mechanism to replay the conversations and not the higher 
level protocols.
