RE: [Simple] Windows messenger

But the Messenger seems to have a big problem with the presence
format. The presentity uri should identify the presentity for 
whom the presence data is being reported, but Messenger instead
sends the address of the receiver of the information!? 

The Messenger also does not have any Event header its NOTIFY
messages, and it sends a NOTIFY without any content to indicate
that it is offline.
