Perhaps operating systems should generate a new random MAC address on each reboot. Just a thought.
And if they don't, it should be pretty easy to lash something like this up yourself... Don't most NIC's (or, technically, I guess, their drivers?) still support arbitrary MAC assignment? It was necessary in the dark, evil days of -- ummmm, mind goes blank as I've tried to repress the memories... D-D-D-D-DECnet IIRC, certain bits of DECnet (or at least, certain bits of DEC hardware we had implementing critical pieces of our DECnet) would only talk to MACs that started with (one of) the DEC manufacturer prefixes, so to hook up an arbitrary PC, Mac, Sun, etc to such a DECnet config required either that your PC, Mac, Sun etc had a DEC NIC (rare to impossible) _or_ a NIC that could fake the MAC under s/w control (very common). Last I looked (a few years back) all versions of Windows still supported this functionality, but I can imagine hardware design that would prevent it working...
