Is it at all possible to output the shadow information that's captured in the alpha of a useBackground shader and be able to use it as part of a shading network. 'Out Transparency' seems like the obvious choice, but it doesn't seem to work. Ideally, i'd like to be able to isolate the shadows in my scene and pipe them into a layered texture node for further processing.

Any Ideas?

Mental Ray solutions are also welcome..

I don't know if these will do the trick, but have you checked out the "hidden" Production shaders for MR?
