I am no longer sure about what problem we are trying to solve with "pull".

Is the issue getting all messages (acknowledgements, Faults and inbound 
business payloads) *back* across a firewall that permits only outbound 
communication?  If this is the case, do we need to further worry about the 
system at the other end not supporting immediate (synchronous) acknowledgement?

Is the issue supporting senders and receivers which are not continuously 
available in some slightly-more-efficient manner?  That is, are we avoiding 
one side resending while the other is off line?  If this is the case, an 
asynchronous pull would make sense.

ebMS 2.0 had an SMTP binding that seemed to cover both cases...

thanx,
