Anche il compiz di freedesktop si è mosso in questa direzione:

I've added configuration support to the dbus plugin. I haven't done much
testing so let me know if you find any issues with it. You can find some
usage examples in the dbus plugin code.

This is what KDE needs for compiz configuration support but you can of
course use it for other configuration systems too. E.g. writing a simple
daemon that monitors a text file and use this dbus interface should be
trivial if someone wants to do that.
