Thanks. That is a bit different than what I was thinking
about but it might work for my purposes. Thanks also to all
the other people who made suggestions.
It appears to me that ther are 3 distinct approaches.

Scientifically, I can say this posibilty goes to 0...
It is a random ID (not a totally random but based on the current timestamp)
