I have seen very long conversations about this (maybe on fusebox list?). It
depends on what OS you are on as to how random it is. On some it's not as
random, on others it's really random. I don't particularly care if they are
random or not. We primarily use them as PKs, and it's not too important
that they not be sequential.
UUIDs were not created for use as secure tokens or anything like that, just
a universally unique way of identifying items or keys.
