Can Instapaper use Newsstand to get automatic background downloading?
Probably not. The specifics are under the WWDC-attendee NDA, but I think I’m safe to say that only Newsstand apps get access to background downloads, and there would be a number of downsides to making Instapaper a Newsstand app. It’s also unclear whether this sort of use would be rejected. And since it might be right on the edge of permissable, it’s also a high risk that it might be approved and then later pulled from sale, which would potentially be very expensive. I want to wait and see how other non-publication apps, such as feed readers, handle Newsstand before I’ll consider it. But it’s probably smarter to wait for Apple to possibly give more apps automatic-background-download abilities in the future.
