I did not knew about DigestColumns, and it would be a solution, but I  
also have to deal with some legacy passwords stored in crypt()'ed  
form, so I cannot use it out of the box.

But I can see how it was implemented and do the same.

Regardless, if someone is kind enough to answer my question: is there  
a clean way to have some function or method called whenever a field  
changes besides overriding both set_column and insert?

Thanks,
