THREE.OculusRiftEffect feeding 2 cameras

Currently I'm using the OculusRiftEffect library, that is fed by 1 camera, in a Node.js app.

Now I need to fed my app with 2 cameras in order to generate stereoscopic vision. But I'm having some problems figuring out how to do it. :\

Currently I think that I will need to develop my own lib. But before going deep into that, anyone know of an alternative?

Thanks in advance ;)
