I've just looked briefly at a couple of D-BUS articles and think that it 
will work, but seems rather OTT just to provide progress information to 
a GUI application. Perhaps if libgnokii allowed a callback function 
pointer to be registered for internal event reporting, and a separate 
module (linked as part of libgnokii or gnokii?) provides a default 
callback function that sends these internal events as D-BUS events, or 
Win32 messages (since D-BUS does not exist on Win32 yet :). This gives 
applications the chance to replace the callback with their own handler 
outside a D-BUS environment (BSD?), keeps the event reporting within 
libgnokii simple (just a call to an event dispatcher which in turn 
checks for a registered callback function) and keeps things working on 
Windows.

My 2p worth.
