Totally useless for this particular problem, but I've wondered about how to improve basic line following for FIRST bots. I think you could use a relatively fast line sensor and just basically wave the thing around where you think the line should be. And you keep track of where the sensor is with a potentiometer, so you end up with an analog (ish) value for the position of the line instead of a digital value from 3 or so static sensors. I think it just depends on if the sensor would acquire the line in a fast and predictable manner.
