UUID v1 only _very_ roughly ascends -- it recycles every minute or so. This probably wouldn't matter too much though... Even still, an algo to give you ever-increasing uuids is easy -- just go YYMMDDHHMMSS etc. Then you can append something like a UUID v4, or something shorter that can still strongly guarantee you uniqueness, and you've got the best of both worlds. I think...
