Yeah, I did a little reading between there and here -- it does seem quite unlikely, but possible. Is there an alternative that's in the same ballpark, but not what angus suggested? I'm guessing not -- unless there was something inherent in my dataset that I could take advantage of. I'll probably go with MD5 -- for my needs I'd be able to detect a duplicate hash should it ever occur and deal with it then. Chris
