have you spotted in SIP/SIMPLE specs what has to be sent when the 
presentity is offline? My quick google was not that succesful. Maybe 
Inaki has the specs more fresh indexed in memory and can help.

I based my assumption that the sip/simple presence server should not 
generate itself a presence/pidf document with status closed/offline 
since the pidf has a <tuple id="..."> node that is generated by 
presentity device.

Cheers,
Daniel
