Neither of those will be of any help in making one-way glass. If you 
make a box with one side dark and the other side light, you will either 
see the dark side directly or through the light side. I'm not sure how 
you plan to use the slope pattern...I think it is idependant of the side 
of the surface it is evaluated at.

Anyway, in a one-way glass window, you are unlikely to be able to tell 
the difference between thick glass and single-surface glass. With smart 
lighting and reflection values, you should be able to get an acceptable 
effect, otherwise using interior_texture or actually changing the 
texture depending on the camera location is probably the best way to go.
