I still believe that coming home to find a message ("hey!") which I  
have already replied to while I was at work would be confusing at  
best, and harmful at worst.  Imagine: "sell 50 shares!".

If there was a protocol for notifying your other resources that a  
particular message had been handled somewhere else (or some other  
solution), then I could get behind this more.

I often find that the people that want what the SIP folks call  
"forking" are either using a client that doesn't set priority to 0 on  
auto-away, are running multiple resources and haven't configured  
their priorities in any interesting way, or have a server that  
doesn't make a good guess on priority ties.
