Maya Curve Based Facial Rigging Tutorial

Hey there.
Im looking for a good curve-based facial rigging tutorial but so far I only found the DT (which I didnt liked, maybe cause it used a cartoon character and I built a realistic one).

Is there any out there that shows at least the principles? The most complete, the best!

Thanks!

"The Art of Moving Points" by Brian Tindall looks really good, I haven't read the book but I've read and watched all the available information on his site, very impressive.
