there are two ways:
- end-to-end - the clients handle the presence requests  - the messages 
are sent from a client to another, the server just routes them. In this 
case you don't need the PA module. PA module is usefully for clients 
that do not have presence support implemented (like phones or adapters). 
MS Messenger has presence support implemented and you can see buddy's 
status.
- client-server - here you need the PA, the clients subscribe to server 
and this informs the clients about user's status.

For file transfer it has to be end-to-end and you don't need PA at all.

The main developer of PA module is now Jamey Hicks. Perhaps when many 
users will use and test PA and they consider it stable, it will be 
released. we have no real application of PA at this moment and I cannot 
say a timeline.
