  Backface culling?

My (or better my scene's) situation is as follows:
I have a room with some mirrors in it. When the camera is located above  
the roof of the room, i cannot look in because of the roof. So i removed  
the roof from the scene and everything looked pretty well at the first  
glance. But at closer inspection the mirrors do not mirror the roof  
anymore (because it has been removed).

Is there a possibility to enable backface-culling relative to some vector  
(in my case the eyevector)? So i could look through the roof and it would  
be mirrored correctly. If backface-culling is not the way to go, can i  
assign different textures for each side of a triangle in a mesh? I tried  
to duplicate the mesh with different triangle orientations and normals but  
i've got some strange visual problems then.

Regards,
Jan
