Interesting. I'd probably just use Xcode though. I think this is something that Tumult should just build into Hype. The project should be exportable to iOS, Android, Windows, OS X, Linux. That would be less frustrating for us developer and probably lead to more sales for Tumult. It's not hard to do, just annoying. And since it only needs to be done once, it should be automated.
Meanwhile, it's nice to see an alternative option.
