The way presence information is collated in KDE is that sources of presence 
information (chat applications, implementing KIMIface) _do_ signal presence 
changes for registered contacts.  Applications use this by instantiating a 
KIMProxy object, which listens for the signals, computes the overall presence 
of the contact and signals the application.  The application sees presence 
changes in terms of KDE addressbook contact UIDs and a presence enum.

So in our case we do have a small glob of state on every app that uses 
presence information.
