Part of hte problem with UUIDs is who's definition you go with as several
entities have things called UUIDs and/or GUIDs. Microsoft has one
definition. Guid.org has another. I think ISO has yet another. Some
use an algorithm that includes your MAC address which raises some
hairy privacy concerns.

The nice thing about most GUIDs is that they're really just a combination
of some location, a timestamp, and some hash which make it so that
you can create an insane amount of them algorithmicly...
