multiple bipolar motor

Hello Arduino gurus,
I’m new to this device, and was searching for any information/examples on multiple bipolar motor controller. Specifically, I would like to connect the Arduino Duemilanove to as many EasyDriver Stepper Motor Drivers ( from sparkfun) as possible (4 bipolar motor connection would be ideal).

Does anyone know if this is possible? (possibly relevant side note, I intend to use labview for the overall control)

Each EasyDriver requires 2 digital pins and a ground connection to the Arduino. So, 4 of them would only require 8 pins. The Duemilanove as 13 digital pins, plus 6 analog pins that can be used as digital pins, so you should have no problem driving 4 stepper motors.
