What about taking a lead from systems like Novell's ZENworks, where
the system boots via PXE every time, but to continue loading the boot
image, the user has to hold down a key? Otherwise it drops back out
and boots as per usual.

This way you can leave your ip helper configuration alone, and don't
need to fiddle with your DHCP server configuration.

If there is really no one local to the machine that can press and hold
a key for you, maybe one of the things the boot image could check for
is a per-system flag or something to determine whether to continue
loading the image.

cheers,
Dale
