this makes much more sense than extending IMAP. It should be really easy
to write a CalBackend-based class which, via gnome-vfs, allowed the use
of remote calendars via any protocol supported by gnome-vfs. In fact, we
could even make the cal-backend-file work for this, since it uses
gnome-vfs itself. It would be just a matter of fixing the places where
it assumes it's local.
