That looks like a lot of the changes i've made to knoppix as well, however, I'm having a hard time switching the default WM.
I've changed it in several places, everywhere I've found in these howtos; but everytime I get it to boot into fluxbox I get an error about kdeinit not found. How do you get rid of that? Also, if you happen to know this... how do you launch an app and make sure it's persistant after launching the WM, a la knoppix-MAME?

I've got a cable modem that I COULD host your iso on, I have a couple of mine on there, but it's slow as heck (128kbs upstream). I'd like to test your's out, nonetheless, you can reply in this forum or email: bhsx AT bhsx DOT yi DOT org
