You missed gluegen-rt.jar

^^ Do not include the native jar files as long they are in the same folder
as their 'pure' java counterpart.

Yup, see above.

Pls update your browser cache, it's there.

It is possible to employ such mono-parts strategy sharing an FBO, ofc.
The StereoGLEventListener.reshapeForEye(..) receives the EyeParameter,
which includes knowledge of the target eye (left/right eye).

StereoGLEventListener extends CustomGLEventListener.

CustomGLEventListener.display(..) receives
the bit CustomGLEventListener.DISPLAY_REPEAT for the right eye.

Surely the Stereo*Renderer is designed for correct asymmetric FOV rendering,
see StereoDeviceRenderer API doc.
However - surely a shared FBO blended in the background is a great idea
to reduce costs.

Great that you like it.
