agreed; we're already on our way to Wayland (excuse the pun? :) so this is a 
key concern. it's much nicer to port centralized code that then extends these 
changes automatically out to all applications (a prime design idea embodied in 
so many of our libraries) than to have to hunt down code all over the place 
and port them.

in this case it probably only needs to use the kded daemon. the applet or tray 
icon is likely irrelevant.
