The current MCS daemon behavior sucks.  It's the only process allowed
to *set* config values, and no other clients connecting to it are
allowed to do so.

No, the current MCS daemon has nothing to do with kiosk mode.  Kiosk
mode is implemented (poorly, in many cases) in each individual
application.  It's totally settings-manager-unaware.

Yeah, this is one of the nice things about current MCS, but really, all
it's doing is abusing XSETTINGS for this, and I don't think it's
totally necessary to have network transparency for settings as well.

Yeah, I agree.  This also lowers the barrier to writing another
implementation of the spec.  The part that knows about parsing
special .desktop files to deal with settings panels can (in Xfce's
case) run in the same process as the settings daemon proper, or not.
Let's leave the UI out of the settings manager proper.  (Though we'd
need a separate, likely Xfce-specific spec for how to handle the
settings panels.)
