If they don't want to change their layout, why not let sites like PadMapper build on it the way that it has been doing? That way, old-fashioned users can keep using just CL and people in need of something slicker can use PM+CL. I also don't understand why classifieds content is proprietary? Aren't they just facts? Please can someone explain?
