5. It still probably won't work great on anything but a flat floor.

Woah! First off, I'd like to thank you all for the amazingly immediate responses! Second, based on recent posts, I'd like to put something out here: we're a one-season team with only two or so of our members having any previous robotic experiences (myself and one or two others). Additionally, this is the first time I (and I believe my teammates) have gone beyond the LEGO Mindstorms NXT (r) level of robotics. In a nutshell: I''m really not sure what to think of some of these posts, much less what they mean! I know what an encoder is (measures/counts rotations), but I don't see how that would be beneficial to a holonomic drive.
As for code, if we decide to go with mecanum wheels, they'll almost certainly be driven using four jaguars and the code for holonomic drive found in the WPI Robotics Library in LabView, without any changes.
Thanks for understanding our current lack of experience in pretty much everything at this point!
