Well, this will sound like an cat barking but... i really have to ask the comunitty to try...
I read much about remastering the knoppix and other things.. I tried to make a small customizing in my knoppix.... but it failed.. very much !
No i could suggest to you.... Why dont u make an Windows( ) very small software that is capable to choose:
> Distros inside debian....
> Be bootable or not, like knoppix is!!!
> The packages avaliabes in stable, testing and even in unstable!!!
> Make the package depedencies files automatically
> the conf files setup based on the hardware u have!!!!
> Make the iso files to you!

This might sound really stupid, but i have a very limitted experience in linux, i am used to windows ....
It would be very useful to change the windows by the freedom that linux based system offers to me.... It would be much easier (wrong spell?) to convince the MS user to migrate to linux.....
I really hope u could do this....
By now, i will just thanks the time all will lose reading this....
