cPoc fyi...

Just to note, and clarify, the closest point on curve script and node i mentioned is different from the one you'll find under create deformers - point on curve.

That particular point on curve deformer uses the curvePointConstraint command, which is basically constraining cvs (or partial cvs) to a locator.

My script/node will do the opposite - a locator/transform can be constrained to the curve, so if you have the curve skinned/deforming/moving, you can have something stick to the curve. again, its the same as the closestPointOnSurface node, but it works on curves.

anyway, just wanted to clarify since a couple people asked :)
