I meant that having it be a portal to a separate scene file wouldn't be 
any more useful than being a portal to another part of the main scene. 
You could make it "link" to a portion of the scene that is out of sight 
instead.

Well, it requires an object to define the area the portal occupies, and 
making it a pigment type like image_map makes it a lot more 
versatile(you can use it in texture_maps to make the portal irregularly 
transparent, and turbulence might be interesting.
For my version I had been thinking of an "is_portal" attribute for 
objects. This would have been a lot more limiting.

A couple more possibilities for the name:
ray_transform (This one is very precisely descriptive of the process, 
but doesn't give a good idea of what it actually does. I don't care for 
it much.)
magic_mirror
looking_glass
