Except Kevin is wrong. I've tried pushing unpowered mecanums sideways (software testing for 2337 in 2010). I was physically unable to push the robot sideways. Along the diagonals was a different story though. Still not easy but most definitely easier. None of this involved any sort of fancy software which would enable the wheels to hold position.
As for grippy mecanums, if you ever get a chance talk to 357 about their process. Their wheels have quite a bit of grip and they are one of the few teams I've seen use mecanums well.
However, I am a firm believer in the theory that if you are pushing with a mecanum wheeled robot you are doing it wrong.
