The only possible thing I could recommend adding would be some sort of "auto-adjust" for SBS stereoscopic images that aren't quite correct for display (distance between fisheye circles is not quite 65mm and they need to be nudged a bit). Otherwise I prep the image in something like StereoMakerPhoto Pro and adjust the distance between the two circle fisheye images there.
