Here is a link to a similar feature in Lightwave3D.
http://www.newtek.com/lightwave/highlights2.php#BoneDynamics

Basically... I'd love some way to have a chain of bones that can simulate a piece of rope or string and be pulled from one end. Then be able to BAKE the results into keys so they can be manipulated and fine tuned.

The bone dynamics would be a good start towards this. And with all the new bone and IK features... it may actually be possible! Don't know really.. just hopeing!
