  1. A user sets generic preferences, upon which her agent (browser) automatically acts.
    She can now browse the Web seamlessly.
  2. She encounters an  site with "exceptional" practices outside her generic preferences.
    Perhaps a sports news site wants to collect her favorite teams for a customized news page.
  3. The user is prompted if she wishes to consider other alternatives, consent to the exceptional practice, or to go elsewhere.
