My understanding is that caveat covers version 4 GUIDs where the UUID is
generated w/o access to a IEEE 802 address and the node is then set to a
"random" number. Those generated w/the 802 address (version 1) would be
unique.

However, I don't know which version the iSeries generated (guess I could
look but I'm lazy) and in fairness I know MS switched to version 4
w/windows 2000.

Walden,

Don't know that I'd call it a bug.  Since the standards specifically say
that "is either guaranteed to be different
  from all other UUIDs/GUIDs generated until 3400 A.D. or extremely
likely
to be different (depending on the mechanism chosen)"


But I looked into it again this morning and it seems IBM felt it was a
bug

Guess I should have followed up before saying anything!
