This is a valid point.

What booting system does the LiveCD use after transferring it to the
USB stick?  Perhaps a middle ground would be to create a wiki page on
how to add the netinstall kernel/initrd to your own media.

All I see there are instructions for the various methods of booting a
kernel and initrd files from different media (or via PXE).  As I said,
if you can get the device to boot off the kernel you specify that is
all you need, no special sauce required.

I didn't make the above statement, but I expect a newbie will probably
have or will obtain a working optical drive.

On the other hand, knowing how to create a linux boot media is
probably a good lesson to learn.  Newbies don't become experts by
magic, they do it by learning new skills.
