Another challenge I have is on one site, users keep signing up multiple times with more than one account. That's a problem, as multiple accounts is against our site's TOS since we frequently have votes that are one-vote-per-account. Our legacy system that we killed when we moved to Drupal had built-in IP logging every time a user logged in, so we could go in and check IP addresses in case we suspected a duplicate user. We could also see the IP address someone signed up from, and match that against any recently logged IPs.
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 :(
Does anyone know of a similar tool for Drupal, or is this another module I'm going to have to write myself? :-)
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.
