[MAC for software keying]

There's a program I used a while ago (scanning program for Unices IIRC) that
asked for a key string during installation.  The string was generated by
sticking your machine's MAC address, hostname (and possible OS and IP
address) and a few other bits into a CGI form and hitting Submit.  This
meant that if your NIC blew up or you renamed your machine, you needed a new
key.  Of course, my NIC blew up while I was copying the tarball up to the
machine.  C'est la vie.  (I got my own back by renaming the machine and not
adding a CNAME to DNS.  Ha!)
