You are misunderstanding a bit; Asterisk can use an XMPP server and 
PubSub to *distribute* presence information among a cluster of Asterisk 
servers. This information is not intended to be directly sent to XMPP 
clients.

Yes, in order to let other Asterisk servers in the cluster know about it.

Asterisk does not support 'user' presence; it supports device and 
extension presence. In some applications these can be used 
interchangeably, but in others they don't match up very well.

This is exactly what 'distributed device state' is all about, whether 
you choose OpenAIS or XMPP/PubSub to distribute the information between 
the servers.
