How about something where users could sign up to have the site 'off' for them during hours that you (pg) specify? That way we couldn't adjust the time and cheat ourselves, or lift a self-imposed block just because we have 5 free minutes before lunch. Also - it would be good if the decision to sign up to have the site down for those users was irrevocable for at least the first couple of weeks.
I understand this is scope creep to your original idea - but it might be fun. And it could be a historic precedent - the first feature added to a site which would block user's access to that site.
