So RFC2616 says "202 Accepted:"
  "The entity returned with this
   response SHOULD include an indication of the *request*'s current 
   status and either a pointer to a status monitor or some estimate 
   of when the user can expect the *request* to be fulfilled."

Except I might legitimately send back a 202 Accepted following 
securing the message in a database or putting it onto a reliable 
message queue, well before any SOAP processing has taken place.

For my money the ability to send a RX ACK in a 202 is interesting
and falls well within RFC2616's 202, but presumably would require 
SOAP processing generating MU faults etc, so would require more RX 
specific instruction in such a note building upon Dave's one-way
