Splinecontroller.js from wiki not working in Unity 3 Beta

I know its a Beta but just wondering if anyone got the splinecontroller.js to work?

It works ok if you fix the one compilation error (Change the word extends to implements as the error says, line 90 of SplineController.js).

On the other hand, the js version didn't work properly in 2.5+ either, as it uses new with MonoBehaviours. It doesn't actually stop it working right, but it does spam the console with warnings.

I would suggest instead using the c# version, which has the bug fixed
