A good, cross-platform, UUID library is extremely useful. Without the guaruntee of uniqueness provided by MAC address + time, it isn't as useful for my situation. We have data generated across a large number of disconnected computers (I highly doubt there would see a duplicate, but in my case, we can't take the risk).
This could also be done in a way using the name-based guid create function.
See http://article.gmane.org/gmane.comp.lib.boost.devel/154791
I thought about that, and for most people I think this would work well. The most obvious way would be to use the computer name, since that is usually unique. However, in my weird situation, we have computers all over the world, and they all have the same name. So, I'd have to come up with another way to get a unique name. We would most likely just keep using the same mechanism we have now.
I do like what you have done so far, my situation is a bit on the extreme side with our uniqueness requirements.

Maybe this solution will never work in your situation, I'm not sure. But the 'unique computer name' could be the mac address instead of the computer name. If not, I would expect that there is some piece of information that is unique for each of your machines that you could use. But maybe not. I hope that one day this library will have a solution for you. Andy.
