I thought it would be interesting to have a script or utility that could turn a normal linux system (such as a firewall/nat/dhcp) that most of us have into a knoppix boot server without having to be running knoppix already.

Perhaps just mount the cd or ISO on that system and normal windows/linux/unix clients get their IP normally, but if one wants a boot image (pxe/etherboot) then have the server send out a kernel. That way someone could set up Linux "terminals" around their house/business that give web access that don't have to have a local drive or a separate knoppix terminal server. I've been doing a lot of playing with knoppix TS but I have to disable my local DHCP server to enable it. If the two could be combined into one system that runs a different linux (in my case RH 7.2) but still distributes Knoppix, it would be really cool.
