I love node based rigging :D. Here is how ive rigged the "Follow" attribute of the eye controls so they can either follow a master control so the eyes can follow an object, or they can follow the head, so the eye's stay fixed with the heads movements.

I first used some parent constraints but the popped when I changed the weigh if i wanted the eyes to stop following, so using nodes I was able to blend the two parent objects without using constraints. This way a blend of 0.5 means 1/2 of the position is coming from the head and the other 1/2 is where the master eye control is, this means I can smoothly blend between 2 controls and avoid any annoying popping.

In the long run this means i can avoid any extra counter animation if i want the eyes to follow different thing then his head, without this id have to tweak about with key's trying to hide when the eyes pop.
