Thanks.
Elvira, Gyuri,
Partial extrude was indeed the simplest method and worked well. I'm
embarrassed that I didn't know it was there after working with Maya for
over 4 years.
Aleksander,
Your method, while a bit complicated is extremely intriguing. I've had
need to pefom curve deformation on objects in the past and this sound
very suitable to teh task. I'm not sure I understand your procedure
though. I can get the wire deformer to affect the lattice, but I'm not
sure I understand the use of the blend shape. Thanks again.

After this operation you end up with 2 curves and your original, you can delete
one of the new curves. Use the other one by going into its channel box and
animating the parameter[0] under the Inputs tab to make the curve grow.
