The setup used at the kick-off demo allows you to calculate a heading and distance to the beacon. If you think of the beacon as the origin of a polar coordinate system, and you know the distance and angle to the origin, you should be able to figure out your position within the coordinate system. With a little trigonometry, you should be able to calculate a cartesian x,y solution too.
