The problem with this is approach is that support for multiple concurrent 
netconf sessions is not a MUST but only a SHOULD, if I'm not mistaken. So 
you cannot rely on this idea as a general solution.

I think you can get only one reply to a request. Perhaps the reply could be 
an immediate "operation started", and then you can issue subsequent requests 
for processing progress, that could be also immediately answered like 
"operation in process (X% complete)" and, finally, "operation complete" 
(with success or error). Sorry if this sounds silly. I'm only a couple of 
weeks worth on NetConf yet.
