Jeff,
I haven't used it, but have kept my eye on it for the last few years. It
certainly sounds like a decent solution if you want more control over
password complexity during user selection.
I don't think it is a service (just my understanding, not definite). They
probably just wrote an extension to the msgina.dll so they could support
additional complexity checking. If that was the case, there is probably no
way for someone to know this change was made unless the password change
dialog window is significantly different.
Here's a link to another modified gina:
