For those interested in this type of camera motion, I developed a small camera class that implements spring physics to attach a 3D camera to a moving target allowing for complex motion like 3rd person, first person and chase. Very useful for racing games and such when you want to create a "natural" camera movement.
There's an Away3D and a Papervision version available. http://agit8.turbulent.ca/bwp/2009/01/22/spring-physics-powered-3d-camera-for-away3d-and-papervision/ Let me know if you like it! -b
