DemoLinux already is a Debian-based CD that runs from a live filesystem,
you might want to look at that as well.

I don't really believe this argument:
* making a chroot environment is really easy. Basically you just grab a
  base .tar.gz, extract it, and chroot into it. That should take you all
  of 2 minutes or so :). chroots also allow you to test distro upgrades,
  which might be hard with live cdroms

That should be really simple, the linucare bbc already does that
for example.

You'll have to wait for Al Viro to finish his stacked filesystems
stuff for the VFS layer.
