That's a missing feature, yes. But I don't think the design prohibits 
implementing it.

At the time KConfig was designed the idea was that one could plugin other 
(e.g; SQL/LDAP) backends directly into KConfig. Personally I don't think that 
this is the way to go (too slow because too much roundtrip delay) and that 
the correct solution is to have a seperate sync-daemon that fetches, syncs 
and re-uploads (config-) files to the server and that applications basically 
keeps using the existing INI-file backend.

Form there you could tweak things a little and instead of using the INI 
backend, write a backend that communicates directly with the sync-daemon, but 
I doubt that would gain you much. Such approach would be awefully close to 
GNOME's GConf btw.

Can you post your stats on the files that get parsed during konqy startup?

Cheers,
Waldo
