Sorry, should have specified: I'm the original implementor. I'm on the paper with John Gustafson, and presenter/live-demoer of the second half the Stanford video. There is a paper coming out with details on the yonemoto -2 hidden bit method... I don't know if it's still preprint or embargoed or what but it is recent. I'm really not involved in the project anymore so my knowledge of the existence of this paper is only due to the courtesy of the authors.
