A similar setup is the "rocker" setup. If you see the Kitbot frame, one hole right in the middle is lower than the rest. The "rocker" or "drop center" lowers the middle wheel slightly to give the same maneuverability as a coplanar with omnis on the corners, but it's harder to turn because all six wheels are traction wheels.
I do like that setup but I alway did not like the idea of letting the robot rock since it seems unstable to me but it is probably fine. Also depending on which way the robot is traveling and weight distribution it could really mess things up. I looked at a nice 6wd setup by team 25 at the NJ regional and in Atlanta. That seemed to drive very nicely. I am guessing how much you drop the center wheels can also make a big difference in driving since I heard from one of my fellow 303 team members that a 6wd drive they tried last year jerked around a lot since they did not drop the center wheels enough.

By the way what was team 1114 using on there drive train? Looked like a 6wd all traction wheel setup.
