Crabbing (or , The Swerve(TM), as we have named it) is an awesome feature. I highly recommend that more teams should join the club.
BUT...
It is a great and terrible thing. It takes excellence in 4 areas to pull it off successfully:
#1 solid mechanical design -- well designed drive train and pivoting system
#2 feed back -- the computer must know the steering angle of the wheels
#3 programming -- this can be a very tricky system to get right, especially using PBASIC
#4 driver skill -- without drive time, the feature will not be worth the resources (design effort, cost, weight, etc.)
If you have the strengths necessary to make it successful, I cannot urge you enough to implement this feature on your next robot.
This is about as helpful as I what to be right now. I guess I will add that you can learn a lot from reviewing old robot photos (not just of our robot but 111 from 2 years ago, team 349 and team 48 last year, among others).
Good Luck.
Joe J.

But now the most important question - is there a practical application for one of these devices on a FIRST robot? - Chris Fultz [more]
