In my experience the hardest question by far in a nontrivial configuration 
system is always how to handle differences between different configurations - I'm 
thinking of cascading systems where you can store differences against the 
baseline as diffs or as absolute values, but it will hardly be easier with a 
cascading system like KConfig *plus* switchable user-level configuration.
I recommend not to implement this feature because it opens a big can of worms 
and it will cause headaches for years to come, and require application support 
to work well.
We have more important things to do. Note there are no wishlist items for this 
(prove me wrong ;).
