Hi Bjorn, The orientation of the view would normally come under the View::getCamera()'s ViewMatrix, usually it's the job of the CameraManipulators to do this, so you could implement the local offsets using a custom CameraManipulator written specifically for the OcculusRift.
Alternatively you could you track the view matrix offset and apply this to the left/right slave camera view offsets, so that it automatically gets handled regardless of the the CameraManipulator applied to the viewer. Does this make sense? Robert.
