What is the maximum number of "Arduino Motor Shields" that can be stacked?

If this is the shield you want to stack, the maximum is 1. Only one can be used on an arduino:

This one on the other hand, can be stacked to make a maximum of 32 motor shields:

The 'problem' with the Arduino shield are the hardwired pins. You can more than likely add a second shield if you cut some of the pins of and wire them directly to the micro-controller board.

Never tried it though.
