I would say that a kded module that queries XSettings on X11 and returns the 
configuration/state via D-Bus to KDE applications is more interesting. On 
other platforms, those settings wouldn't be stored in XSettings, so the 
module would have to convert from the format used there.

But, come to think of it, D-Bus is completely unnecessary there. Just make 
KGlobalSettings or KDesktopSettings have _mac.cpp and _win.cpp files. It 
avoids the extra roundtrip.

Nitpick: D-Bus.

It works just fine over the network. It's unencrypted, unauthenticated and 
there's no default bus over the network. You have to create your own code 
using libdbus-1 directly to open a DBusServer on a TCP socket and connect to 
it, or modify your dbus-daemon configuration to listen on a TCP port.
