Someone else (Xenoarch?) wrote a similar patch, I think he called it 
"hologram" though. (other names that got tossed around ranged from 
"magic_mirror" to "mirage"...)
I just got impatient waiting for it to show up, so I started writing my 
own. It currently works, but isn't very functional yet...I've been 
trying to implement the ability to use a camera as a portal (the effect 
would be similar to rendering the image from a different camera and 
using that image as an image_map, but would be done on the fly), and one 
of the problems is that the camera code assumes it is rendering pixels 
of the output image and that there is only one camera in the scene. (I 
had to make an almost identical copy of create_ray() which doesn't use 
the precalculated information for the main camera, duplicating a lot of 
code...and focal blur won't work for a while)
