If DConf needs to solve this, DConf will be even more complex to both
implement and to get it adopted. You will not only be asking to
application developers: "Hey, change your configuration system!" but
also "Hey, make sure that you from now on use this specific system for
putting that specific application data in!".
Are you prepared to redo most of the evolution-data-server project? Is a
Novell/Ximian developer working on Evolution going to do it? Will
Firefox/Mozilla and Konqueror/Safari and Galeon/Epiphany adopt this?
That's asking for quite a lot adoption.
You will need to talk to a huge amount of application developers. This
way it will take a lot longer to both implement it and to get it
In other words: DConf will be more likely only vaporware.

One thing I learned from my experience as a software developer (as a
profession) is that nothing is trivial (and telling your customer
something is trivial is like shooting yourself through the head rather
than just your foot).
You really want to take a look at the "sharing calendaring and contact
information" of evolution-data-server to know the needs for such a
system. Perhaps it's better to reuse that software project, perhaps not.
I don't think a simple sqlite table (file) and some standarization is
going to do the job.

I don't think the configuration system needs "structured types". The
most advanced type is perhaps the LIST-type. Which is a list of simple
