GRUB, ISO, and remote boot.

[Ken D'Ambrosio]

I know that GRUB can't, by itself, remote boot a live-boot ISO (it needs 
some help from the ISO, itself, which won't be the case, here).  But I 
also am almost sure I can
1) Mount the ISO on a remote system (and export it)
2) pull specific files from the ISO, and use them to create a GRUB 
entry, which then
3) boots up with the files pulled from the ISO, then accesses the remote 
system's exported ISO for the final boot process.

Does anyone know which files need to be pulled for this, and/or how to 
create the corresponding GRUB entry?

Trying to make this happen so that I can access remote hosts over a 
terminal server and do remote installs without having to have someone 
lug around a DVD and drive.

Thanks!

P.S.  Yes, I know all about PXE (which I can't use -- not only doesn't 
the hardware support it, but I have no control over DHCP at the remote 
sites), and also nifty things like HP's iLO supporting virtual 
network-based media, which, alas, is *also* not applicable here.  Wish 
that it were.
