Booting from ISO installed on USB stick

I realize that this topic has been brought up before, but I'm not sure if anyone is trying to do this without having another OS on a separate hard drive installed in their machine. I have been through every post in this thread: http://www.knoppix.net/forum/viewtopic.php?t=11796 and haven't really found anything that definitively says it will or won't work.

I'm trying to boot from a 3.8.2 ISO image installed on a USB stick attached to a machine that has no internal HD or CDROM. I've downloaded several sets of grub files and whatnot, but have been unable to find a clear explanation or walkthrough of what needs to on the USB stick and how it needs to be modified to point to the ISO on the stick, rather than an ISO on an interal drive. I have found that the stick is recognized by the machine at boot, so at least I'm over that hurdle, but I'm wondering if what I'm trying to do is even possible.

Does anyone know?

well, from my limited experience with linux, anything seem possible.

There is some information on this topic in the English Kanotix Wiki (http://kanotix.com). But maybe it is a simpler and more flexible solution to boot your diskless computer over the network, using the Knoppix terminal server script.
