AFAIK all LInux distros, and PXE, send no UID with their requests.

Actually, changing the UID would be even easier than changing the MAC
address. If the user can change the MAC address, and that's a
problem, then you mights as well pack up and go home ! It's the
nearest thing we have to a unique and unchanging identifier - and as
you've observed, it's not exactly hard to change.
