>In addition to what George said, the Session object also has Private data sessions. Also, in VFP7, it has been enhanced to that it's native methods are not exposed to the public interface. Much better design this way.

In addition, the development-time advantage of using one of the visual classes like Line or Custom for COM object is that you can work with them in the Class Designer.
