hm, I must have been sleeping or something..

if the problem at hand is just to but kick of unattended from network
you could use my solution (which I currently still use to boot ghost)

I use grub on all machines with two menu items:
##################
title HSG
dhcp
configfile (nd)/grub/menu.lst

title Win2K
chainloader (hd0,2)+1
##################

the second entry is just there in the case of a network failure,
or other problems..

then I can change the menu.lst file on the server as needed, for example
to default to do a unattended installation. For example:
##################
title unattended
kernel (nd)/unatt/vmlinuz noapic z_user=XXX z_pass=XXX 
z_path=//192.0.2.8/install
initrd (nd)/unatt/initrd
##################

Note:
* grub needs to be compiled with all nececssary network drivers for this
  to work
* worth trying would be "bootp --with-configfile" instead of just "dhcp"
* pxegrub exists also, so even blank machines could use this
* there is a "password" option in the config file, using which, you can
  get a different menu after entering a password (so that users can not
  see options which they should not)

I do not yet know a good solution to tell exactly one machine to boot
something different exactly one time. Possible attack vectors would be
scriptable dhcp daemon, tftp-daemon with support to send a client the
output of an executable (cgi-bin like) or hacking grub to do special
things.
