[Tweener] Create lookup table w/Tweener?

[Mitch Rosefelt]

I have an app where I need to bias the motion of one object based on the 
motion of a different object - a timeline slider.
I use the % of the "driver object's" full range to position the "driven" 
object.
The driver is positioned w/the mouse, so I need to lookup the value on 
the fly.
Is it possible to use tweener to create a lookup table so I can bias the 
% of the driver's motion w/an easing function?
Thanks.
