Certainly, it will also make roaming easier.

Does that first step make sense? I think you would like to be able to say on a
KDE-wide scale "Use the SQL backend instead of the .ini files" I don't see
the point of using this only for programs specially designed for it.
As a bonus you will instantly meet the "2 programs rule" ;-)
More seriously though, I would very much like to see an implementation of
this. I'm especially interested in the performance part. I'm somewhat afraid
that the solution that you outlined may be rather slow. I myself played with
the idea to keep the INI-Backend but have a file-requester service that
downloads and uploads config files when needed. The applications themselves
would then still access the (downloaded) files from local disk. The advantage
of this approach would be that it might also work for files that aren't
strictly config files (e.g. the history file of konqueror)
Anyway, I would like to see this ending up in CVS
