[Serusers] PA module status

[Juha Heinanen]

jamey,

thanks for working on the pa module.

i have a general question on this one.  how does the pa module know if
the user is willing to let someone to subscribe to its presence
information?  is there now some standard way for the presence server to
ask about it from the user or how it is done?
