Right. Otherwise you could just change the texture.

Say, from a mirror in the room on the "subject" room, with the camera in 
the "observer" room.

Uh...why? You would still need a close look at it.

Well, as I've been saying, you can probably get a reasonable one-way 
effect by good lighting. But I don't see how the slope pattern can help 
here. Are you using the object pattern to only silver one side of the 
glass? That's a little overkill in flexibility, and gradient would 
probably be as fast, but it would work.
