/me laughs. I would have just gone around with a clipboard. Could have been done in 45 min. instead of two days. Although, admittedly, your solution is much cooler technically.

As an aside: I did the same thing you're doing at an ISP I worked at. We went with a new administration package that needed to know the passwords for our several hundred dialup customers, and we didn't keep them in plain text. I ran a brute force cracker on them for a few days and ended up only having to get about 20 of them to "reset their password for security purposes." Most of the passwords were easy stuff like "larry" or "fish" or something equally inane.
