I like that idea. Someone also pointed out that it could be a live video feed online. Just take the bits (in pairs, left and right shakers, or singly, just left or right shaker, or some alternating choice of the two) you need in the way you want. As I say, I like the idea of making the random bit-stream available to users.
And, as you point out, given it generates randomness by tossing physical objects, it is naturally a low bit-rate machine.
