HI Christoph, I would recommend setting the stereo yourself in osgViewer using two slave Camera, each of which renders to a separate FBO based texture, and then have a third slave Camera that rendered a screen aligned geometry with the textures plus any shaders/state that you want. The osgdistorion example does this for a mono scene, but you should be able to generalise this to more cameras.
A more extreme example of using multiple RTT slave camera can be found in src/osgViewer/View.cpp which the View::setUpViewFor3DSphericalDisplay(..) method sets up six slave Camera for six sides of cube surrounded the eye point, and one slave Camera that composes the result into a single distortion corrected image that gets rendered onto a fish eye lens inside a spherical display. In you case you'll just need to set up the camera offsets for the stereo yourself for each of the slave Camera and not use the OSG's default stereo settings. Robert.
