The P&S backend on Maemo is currently read only.  Have you looked at classes 
provided by the System Information module, specifically the QSystemScreenSaver 
class.

There isn't a shared ontology between platforms.  Your application would need 
to know the path to the published settings.  These are likely to be different 
on different platforms.

Set the path property of the ValueSpaceSubscriber objects to the appropriate 
value.  The value of the key can be accessed via the value property.
