I get the desire here, but it feels like there's so many scary reprecussions to limiting cert lifetimes so much. Someone's out using an offline-capable map app on an tablet, then 2 months latter it breaks.<p>There's WebBundles which allow for interesting sharing. But it turns out there's some random cybersecurity document saying DNS data should never be cached for more than 7 days.
