It would also be something else that would have to be maintained and
debugged. Which i would be starting from scratch. The OSSP
UUID library is at version 1.3. From this I infer that he has spent
some time maintaining and debugging it. The less duplication of
code and effort the better.
There may be a problem with using the library as a core type though,
due to windows portability concerns. That said, it would probably
be easier to port the underlying library than to start from scratch.

I was thinking of cryptographic applications. Then, to use an
example from another domain, initial TCP sequence numbers should
be random (i.e. unguessable). A problem with TCP perhaps. It's
been a while since i've read over my copy of _Applied Cryptography_,
but I seem to recall that unguessable numbers were sometimes useful.
