It could be done in some cases using no_image and no_reflection. This 
require that your main part don't have reflective objects. You may also 
need to use light_group.

In the main part, ALL objects are no_reflection.
You have a single mirror object acting as your "portail".
The "world" seen in the portail have no_image for all of it's objects. 
It can also be placed to be totaly out of view from the camera. In this 
case, you can forget no_image.

Use light_group to acheive different illuminations for each parts.

It can be possible, but tricky, to have more than one such portails. You 
must make sure that you orient each mirrors to show distinct areas and 
that the content of any area never cast any shadow on those from any 
other areas.

The secondary areas can have mirrored objects, just make sure that you 
don't see the wrong parts in those reflections.
