All you're concerned with is that the output speeds match eachother. This can be done with gear ratios to get them close to the same speed and shaft encoders to take care of minor variations. It's very similar to the way teams use shaft encoders to make sure their tank-style drivetrain goes straight.

"Limited maneuverability" isn't in the vocab of a holonomic drivetrain. Both our and SPAM's 'bots were of the 4-wheeled variety last year and they sacraficed nothing in terms of maneuverability.

Take a look at Evette and SAM if you'd like.
