A related but different tool is the single login -
http://drupal.org/project/single_login  but, I don't think it does
exactly what you need :(

I think that's the case that you'll have to write it.

You probably know, but in some cases there are whole companies, ISPs,
and even countries behind a single IP.  I guess that your audience is
focused enough that you won't worry about that, but it should be a
"Note:" in the README of any module like this.
