| - Diskless client is booted sends out a bootp request, with the
| broadcast MAC address, which the server responds to.
| - Kernel is downloaded by diskless client and run.
| - Kernel sees the MAC address is invalid, and changes MAC address to a
| randomly selected valid MAC address.
| - Diskless client requests an IP address from DHCP server (running on
| little router box), and gets a different IP address each time (because
| the MAC address keeps changing).

I vaguely remember that DHCP accepts a username parameter that can be
used to select the IP address to be given out.  Is there a way you can
exploit this?  Looking at RFC2131 section 2.1, there is talk of
"client identifier option" to superceded MAC address.
