The initial premise is flawed, implying that moving the surface the plane rests on can keep the plane from moving forward or have some kind of influence over the lift achieved by the lifting surface of the plane.
As we have seen ad nauseum, the resting surface has no effect on the forward motion of the plane. Rather, the moving treadmill will make the wheels turn faster while the plane will move forward as it would normally at any given engine setting. If the forward motion of the plane where to be inhibitted (sp?) or restrained somehow so as to prevent adequate airflow over the lifting surfaces then the plane will not fly. If the plane is stationary, yet somehow adequate airflow is achieved over the lifting surfaces then the plane will fly.
Both sides of the discussion so far seem to me to have made these points but without noting the flaw in the initial premise.
