As I mentioned previously, there is a number
of cases where NULL does not equal empty
throughout the code base (sometimes for
good reasons, some times I am not so sure),
and the Services API generally does not
provide a way to set a NULL and/or an
empty value.  Realistically there are only a
few apps today that try to implement an
alternative to mythtv-setup, so the impact is
limited, but as I understand it the stated goal
was to move towards a web based setup
(using the services API), which makes the
side cases more interesting to address.
