A Traction Control System looks at the all of the wheel speeds and determines which are slipping, then slows only those wheels.
My team is definitely trying to do this [4WD, all independently driven] but we can't figure out one thing:
How do you determine if a wheel is slipping when all four wheels are powered?
Any answer would be appreciated.

You could use voltage and current feedback from the motors with the analog sensors currently available. Through test trends would appear when the wheel lost traction, possibly a spike in amperage. Also if the wheels are independently driven you could use encoders and compare the rotation rate of wheels being driven similarly so if left front and right front are both moving forward, but left front is slipping the rotation speed of that wheel should be faster.
