Dave has got something worked out, but its not ideal. He cannot get a group of curves to work, and is wiring up each one in by hand in the ICE tree.
What he wants to do is emit an objects from one end of a curve and the have it follow the curve to the end.. but he wants to do this to a group of curves. He can make it work one curve at a time fine, he can wire the bizzilion curves up by hand but its not ideal.
