Easy authentication with encrypted URL arguments

Watch a quick video explanation of this

Greg Knaddison and I were talking the other day about an idea of his to provide a token on outbound Drupal emails for simple one-time authentication. If you're subscribed to a post and someone comments, the link in the email could contain a one-time use string that if valid would authenticate you, much like Drupal's forgotten password one-time links. If you follow the link and it's not valid you're just asked to log in as normal.
