This is a great idea. Multiple Live Distributions in one DVD. That way if you feel like one distribution today and another one tomorrow it’s right there. You have to download the Nautopia script. Then all you have to do is copy the boot-related files like: initrd.gz, vmlinuz, and isolinux, into the /dvd/boot/ directories. While the other part of the distribution files sit under the /dvd directory or it’s own directory under /dvd.
