Knoppix use compression while storing the image, so can pack more than normal stuff on the usb. There is a knoppix customization howto available and is fairly easy to customize. You could also customize kubuntu, but imo knoppix is better since the heavy lifting is already done.. ok 64 mb nopix on a flash card or usb stick is good enough. but I need to do the following. 1. customise the distro to lonch my custom menu driven application instead of standard bash. 2. put my own kernel instead of the one coming with it. I don't want heavy modules and other softwares that may be coming with nopix. and thirdly, I need to put speach synthesizer like festival. the card is 512 mb so no problem on that. will I be able to do all this with that nopix 64 mb distro? and I came across a bootloader called extlinux may be that will help me some how.
