OmniWhels are a great piece of hardware. They have so many uses, that it would be useless to name all the possible configurations!
If you want to use it as a holonomic drive, just put a wheel on every of the four sides on the bot. If you want to use OmniWheels to pivot easier and more efficiently, just do a tankdrive, with omni wheels as the far-edge wheels. If you want to be able to easily drift, just make a tankdrive, with nothing but omniwheels!
