I could see this being a strong FTC drive train when there is a large amount of small objects on the field.
You could also put the motors for movement in the screws. I don't think the tilt feature would really be needed.
HOLY COW I never even knew that existed.
I really hope this drive train gets made. It seems to have a few advantages, such as:
1. Small footprint. 4" on each side of the robot or even underneath it.
2. Only 2 gearboxes needed.
3. Omnidirectional, although you would want to test pushing power. I think it would get very good traction in the forward direction.

If it turns out to be more than a gimmick that would be cool.
McMaster sells some conveyor screws that might be suitable for prototyping, but they are expensive. You could put tread on the them with some modifications.

EDIT: Some creative lathe work could do it too.
