Not sure how SL generates UUIDs, there's no exact standard, but if
you're not worried about leaking such information, you can encode in the
current time since epoch (in milliseconds!), and the hostname of the
machine generating the uuid, thus making it essentially impossible to
have UUID collisions, assuming no tampering is involved. You'd have to
have two processes running on the same machine generating a UUID at the
exact same millisecond, with the same random seed, and even that can be
prevented with some locking...
Birthday paradox yadda yadda...
The short answer is, I'd have to RTFS, assuming any UUID generation
happens in the client, rather than the server...
