Mental ray Production shaders in maya

Greetings and apologies for not posting regularly as promised here.Been quite busy with a lot of things lately,anyways has anyone heard of the production shaders for mental ray?these gems ship with both max,maya and XSI but are hidden for various reasons.master zap has done a pretty good job explaining these in this PDF document on the mental images website http://www.mentalimages.com/fileadmin/user_upload/PDF/production.pdf
these shaders basically help you in integration of CG objects in a live action plate.Also check http://mentalraytips.blogspot.com/2007/10/production-shader-examples.html.leave a comment if you still need any help with these.
