please look at how applet persistence is currently implemented. it's very 
simple but pretty effective. i suppose you are, however, looking at how to 
position items in the "desktop applet". personally, i think the desktop 
applet is a design "bump". it shouldn't be one applet (that then has to 
reimplemnt a bunch of stuff that's already there and try and stay "out of the 
way" of the rest of plasma) but multiple applets whose state is maintained by 
a single class that doesn't necessarily paint anything to screen.

essentially, the "desktop applet" really needs to simply call 
Corona::addApplet() when they appear in the $DESKTOP_PATH or when new devices 
are announced and remove them as appropriate (and respondt o the user 
removing said items as well)

yeah, not sure that system is very pleasant. in fact, it's pretty fugly imho. 
the real question is how to handle desktop resizes (which is the point of 
keeping the res in the above example ini file, of course). it would probably 
be enough to record the last seen res for the given layout (which may or may 
not be the full screen (why that is the case is left as an exercise to the 
reader ;)) and simply scale it down if it shrinks. we could scale up the 
whitespace as well for extra bonus points. i don't think it is worth storing 
N positions in a config file, one per pixel geometry, however.
