If you subclass category in this way then I don't think you can't
create new CustomCategory from existing Category objects.

When you create a CustomCategory it will create a Category object but
not vice versa.

And also won't they have to add the CustomCategory to the admin
interface (and disable the existing Category admin forms)?
