Clamp Object Transform with OVRGrabber

Hi,

I am trying to use the OVRGrabber script with the Touch controllers and have objects transform values be restricted to certain parameters. 

As of right now when i try to freeze a gameobjects rigidbody or clamp its vector3 the OVRGrabber ignores these requests. 

Does anyone know how I can solve this without having to modify oculus grabber script?

Thanks!
