I'd think http://www.nongnu.org/python-crack/ is a good start.

I think we shouldn't go too far out of our way for people that can't
follow directions.  Harsh?  Yes, but what we asked of people was
incredibly trivial.  I'd be fine with asking people to log in but I'd
think we'll find lots of people find that confusing.  Logging in and
setting your password is a task that has a clear begining and end.  I can
see people logging in expecting to see further directions and then asking
"now what"?

We've just got so much else to do I'd hate to spend a lot of time and
effort to please a few people that can't spend less then a minute a year
(15 seconds every 2 months) to log in and type their password a couple of
times and the people that complained couldn't do that.

If someone has time to implement some grand scheme, that's fine.  I know I
don't.  The changes suggested about aliases and home dirs are good ones.
