Splitting out the schemas is simply not possible, the schemas need to be shared, since you have shared apps between the desktops! I suppose in
theory glib could be made to do per-user per-session settings (still using the shared key), however that will never happen, and besides this
will all become less of an issue once Unity 8 arrives. Further apart from the case of a user wanting a different theme in different desktops,
there really shouldnt be any major issues arrising from the shared settings.
