I think I remember reading somewhere that Microsoft no longer uses the
Ethernet ID to generate GUIDs, in response to privacy concerns.
However, I couldn't find my source for this fact, so I could be
wrong.  (See http://www.junkbusters.com/microsoft.html, for example,
for a description of some of the privacy concerns.)
