Nice addition, James. Thanks!
To maybe save somebody a bit of messing around, I've found that a FOV of 127.5 degrees with a standard 16:9 aspect ratio will give you the max fishiness without rendering anything that would actually be behind the camera. I think that's what you'd actually see if you cropped a real world 180 fisheye image. It's simple enough to test this for whatever aspect ratio you need by placing an appropriately obvious textured test plane right behind the camera and perpendicular to the line of sight.
Also, I can confirm this OSL still works fine in C4D.
