Is there any way to support a two sided material applied to a geometry, such that entirely different ambient, diffuse, and texture information is applied to the "inside" and "outside" of that geometry?

I am not talking about simple rendering of both sides of a poly geometry, that's butt simple.

Imagine a paper photograph that has an image on one side and that "Kodak" logo on the back side. Does that have to be done with two separate outward facing sets of polygons? There's no way to apply one set of ambient/diffuse/texture to the front faces and another to the back? Even with some of the more advanced extensions that I have not investigated too much into, like register combiners?

I'm looking into supporting 3DSMAX's double sided material in my engine...

thanks for any ideas,
