Predator Paths

I'm trying to determine a good way for predators to move along a non-linear path. So far, I've tried making a custom action in coocs2d to traverse an array of points, which can be set up to follow curves. It works, but this is a bit clunky and requires a large point resolution. Maybe I'll play with some splines / bezier curves later (making use of my Numerical Analysis skills from college).
