Looking to Klaus Knopper interview at PCTechTalk I've read "... Fabian Franz, Author of some of the packages on Knoppix, is currently working on a modularized version of KNOPPIX, based on Debian metapackages and KNOPPIX-specific packages. So, you could use a build system to build your own version and include just the packages you want. "

WOW ! Someone knows when it will be released ?!?

In my opinion a distro like this will become not a new version of Knoppix but THE Linux distro for exellence !!!
