charlie plexing stepper motors

i was wondering, i saw a sample here of charlie plexing so you can use 5 pins to control 20 leds


most stepper motors have 4 wires some 6,.. but with charlie plexing you basicly got 20 (light) switches.
i was wondering maybe the leds could connect to mosfet / hexfet /..?... , and one would be able to control a lot of motors !!

The control could of the engines might be done by using an arays[ ] to set pins in the right order to simplify the various modes and phase turns.

Won't work: MOSFETs share the source pin between control (gate-source) and high current (drain-source) paths, so can't be Charlieplexed without passing the full motor current through a control pin (which is likely to damage the processor).

Also Charlieplexing is a a form of multiplexing, so only LEDs on one row are on at any instant. They cycle through the rows fast enough to fool your eyes, but that is no good for driving a motor.
