Obtaining a unique, "unchangeable" number associated with an SGI workstation

Some of the folks I work for would like to make a reasonably secure
scheme to insure their product runs only on machines they are
licensed to run on.  To do this, they would like to obtain a
read-only number (such as a motherboard serial number) that
could be used as a key to operate the software only on that
machine.  I know mathematica on the Irises has a program called
mathinfo that generates a unique number but I have no idea
what it does to get it.

If there is sufficient interest, I will be happy to post
a summary of responses emailed to me.

p.s.  Ethernet addresses won't quite do it, since it needs
	to run on machines without ethernet boards.
