I see no reason why it requires to be registered in asterisk. The dialog 
for presence is created upon SUBSCRIBE -- and there will get the Route 
set and the address (from the contact header) where to deliver the 
NOTIFYs. As said, the approach worked for MWI subscriptions, some time 
ago, when I tried -- don't recall if I had to do some hacks in the 
configuration, but I am pretty sure was not coding the C in asterisk.

Cheers,
Daniel
