hi,

i feel competent to do what you want. i have also allready remastered knoppix and bring it online soon (a reverse engineering knoppix with kernel mode debugger, disassemblers, and some more "tools of the trade" of the linux RE scene). i also include a self compiled kernel into knoppix, sata disk modules (new laptops need it, wifi modules, ...) just to give you a picture hehehe

please feel free to contact me via pm or email if you still need any help, suggestions, solution proposal, implementation or whatever

from a end users usage perspective i would go for the live cd approach, as probably ppl do not like to free a partition for an installation.

cheers, 0xf001

ps you might see http://home.pages.at/f001/index.html, http://www.rocksolid.at, http://lida.sourceforge.net, for more info about what i am doing, but i really think it is not a problem to implement your demo
when talking about the demo, if you want i can also help you with software protection - meaning copy protection, time trials, ... (utilizing sw/data encryption, anti disassembling, anti debugging, and all this stuff - especially if you want to choose the install approach)
