Since your new algorithm basically encrypts the original hash, I think you could actually write a function to go through and convert all the passwords so that existing members could log in without having to change their pw. But of course when it's uninstalled there's nothing else to be done but have everyone change their pw. Either way you might want to add a warning in the description.

Anyway, nice mod, I was thinking about something like this a while back but never got around to it.
