Third post. The design is being slowly worked on doing things like getting the overall purpose nailed down, building packages for the chips that will be needed, and getting some work done on the DC/DC. Unfortunately even a prototype won't be possible until BFL releases more information on their chips and design. At this point it just doesn't make a whole lot of sense to spend a lot of time on work that might either be invalidated with more information, or just duplicated by the reference design released by BFL. Ideally we'll be able to get really serious about it next week if and when BFL starts releasing documentation.
