I came across this catapult tutorial when I was looking for ideas on
setting up some ropes and pulleys- this method worked well for what I
was doing. It's a set up like Chris mentions below.

That's a very tough job to do with simulations.
Why not create a spiral and deform your rope on it. All the paramerters
are animatable so to wind / unwind it should be easy.
