I've said before, and I think it needs to be said again: e2e  
acknowledgement provides accountability, not reliability. Reliability  
just means you know that the message will be delivered. Telling the  
remote entity when you receive a message opens huge issues for non- 
subscribed users - either you get presence leaks large enough to  
drain the atlantic, or you lose reliability. I'm completely convinced  
that per-hop is the way to go.
