I misunderstood. The thing I was remembering from discussions
with a Windows developer was an universally unique ID
associated with a particular host (obtained I believe by
hashing the MAC address, hard-drive serial number, CPU serial
number, and some other stuff etc.). I thought they were
calling that a GUID, but I appear to be conflating two
different things.
