Do you think Sun would provide this if I asked them?  So if I were to actually have this machine
be on the internet (when I eventually get DSL), it doesn't matter if I have by coincidence the
same MAC as someone else on the other side of the country?

Hmmm...  Someone mentioned you could make up the MAC by using some octets
of the IP.

I also thought I saw a script somewhere for setting the NVRAM at bootime, but
I don't remember where I saw this.
