Well, yeah...if you add Bezier control points on any arbitrary plane in the spline room, and Bezier curves to what is right now a simple sub-division system in the vertex room, you essentially end up with one room.....a NURBS modeller. But at that point, if it is supposed to look like Lightwave, and quack like Lightwave, why not get Lightwave instead? (And don't answer "because Carrara is cheaper." Add all the functionality of Lightwave and see if you can keep the price point down!)
