You need to first make a list of "what to watch" and then find out "who will 
watch." We can not receive dbus signals until it is no one who send these 
signals :)

Already when I implemented the reading switches on the input event devices, I 
considered that monitoring could be carried out in tde_dbus_hardwarecontrol 
that would send dbus signals. But that would require first change way to 
refresh informations in tdehw-lib.
