Practically all of us here are not Knoppix developers or beta testers, but are just community volunteers. There is no way any of us non-developers can give you more information than what is listed at http://knopper.net/knoppix/index-en.html. Some of the developers do visit these forums but you can contact the Knoppix developers at their mailing list at http://sympa.linuxtag.net/wws.
