Indeed, White Rabbit is one of the success story of the open hardware initiative started by Javier Serrano at CERN.

The last one was just a month and a half ago.
You certainly should have a closer look at white rabbit!
You can find a few video presentations online, including http://www.youtube.com/watch?v=YyJTVfebeS4 http://vimeo.com/21909000
