I think this would fall over more often than not. Most developers will not write their code to be resilient in the face of being suspended for extended periods of time. Upon reopening they would likely display error dialogs, or updated version of whatever was saved. In fact, I would argue that it's directly harmful to keep even some of the app logic working. It could cause things like overwriting server state with whatever state was serialized into the saved copy. The usecase here isn't to magically make apps available offline. That's unlikely to ever work well enough that it's worth doing without author cooperation. The use case here is the ability to save some *information* for later access. If I'm about to leave house to visit a friend, i'm interested in saving the directions for getting to that friend. I'm less interested in having an updated facebook feed with me. / Jonas _______________________________________________ dev-servo mailing list dev-servo@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-servo
