You have to imagine the client as being fully diskless. Anything and
everything that a client needs to boot is supplied by the server. There
can be no key on the client that wasn't first shipped to it (ie: in an
initrd) by the server. All thats left is using a DRM-like key in CMOS
somewhere and passing that in with the initial PXE requests, but that's
ugly and requires BIOS vendors to buy-in.
