This may sound slightly odd, but here goes. I want to stop myself from being able to access sites like Facebook full-time from home, and the internet completely at set times of the day. I find that I waste too much time surfing late at night, so go to sleep later than is helpful (for getting a good start the next day). My thought was to get either an Airport Express or Extreme, and get a friend to make lock-down the settings through Parental Controls on the Airport app on their iPhone (rather than on my Mac or iPhone, which I could obviously change). That would handle the access time restrictions - the blocked sites could be handled with an OpenDNS account. Would it be possible to do this with an Airport Express or would I need the Extreme? Any problems I'm not thinking of? And yes, in an ideal world I'd be able to discipline myself, but I'd rather save my willpower for other challenges!
