Can you give an example of when one would want to make an application 
aware that it is "reading configuration from a central repository?".  In 
most of the cases I can think the applications care not where it gets the 
data as long as it gets it.  In the cases where it does need to know it is 
a central store, if you are going to have to make the application aware of 
that anyways why not just tag those keys that should/need be centralized 
as such, you could even have a sub-hierarchy under elektra for all of these 
keys i.e. /system/sw/someapp/netcfg/keys
          /system/sw/someapp/otherpaths/otherskeys
