Check out my comments a few days ago about making a gearbox that drives
multiple outputs, one at a time, from two motors. With some mechanical work
you can easily drive four outputs (not simultaneously) with two motors. And if
you use two rotation sensors you can keep track of their positions
independently, too.
If you want me to, I can privately email you a sketch. One of the commenters
was kind enough to post it, so you can see it on his site at
