I'm unclear what the engineering involves. I have no idea if it is similar or not to ML's implementation.
BTW: I've been wondering if the lower-end DSLR's (Rebels, 60d, etc.) could get a work-around micro-focus-adjustment capability by comparing a high-resolution distance difference between the distance reported by the AF point and LiveView. Or not?
