I do not, however, see how this achieves omni-drive because the wheels cannot roll with a component of motion parallel to their drive axle like an omni wheel or Mecanum wheel.

No, only a single roller needs to be in contact with the ground for this to work since the two wheels Andrew is referring to would be the opposite ends of a single roller. However, I can't possibly imagine how this would result in omni directional movement. Both styles of omni drive that FIRST sees (holonomic, and mechanum) are based upon a wheel that can only produce a force vector in a single direction and will spin freely in the other direction. This wheel will not freely move in any direction when driven, if fact it should produce a torque vector perpendicular to the floor upon which it rests.
Although that could make an interesting Swerve system. Use the torque vector produced by the wheels to turn the modules, basically moving the wheels similarly to a mechanum when it strafes?
