Also, as Douglas Davidsson mentioned earlier on this list (or offline
to me, I don't remember), there is a small privacy problem to keep in
mind, since the UUID contains information about your machine that you
(or your user) might want to keep private.

It's probably worth mentioning that UUIDs also have some limitations,
the most obvious being that there's a maximum rate at which you can
generate them in order to guarantee uniqueness. (I can't remember
what it is, but if you're generating hundreds of them a second, you
need to look it up.)
Historically there was also the issue that some machines didn't have
Ethernet cards (so no MAC address); there are quite a few UUIDs in the
Windows registry that appear to be a bit dodgy because of that
problem. (Windows uses the same UUID algorithm.)
