Yep. To be clear, this mod doesn't alter the vB database at all. It requires access to the old IPB database. It doesn't change the structure, but it does overwrite the old IPB passwords, one by one, as users get synced and login.
Probably not a good candidate to move into Impex, as it requires DISABLE_PASSWORD_CLEARING. The really right way to do this, and support more than just IPB, would be adding "imported_password" and "imported_salt" columns into vB, and then extending the javascript used at login so that you wouldn't have to DISABLE_PASSWORD_CLEARING. That sounded like too much work for me
