Hype could probably run in a web browser. Then, it’s just a matter of tossing it into the platform’s equivalent of a WebView. There are solutions to this problem. Because Hype is only on a Mac, it can’t be an industry standard.
But OK, don’t do Windows – how about an iOS / iPad version of Hype? Pixelmator did something nice.
What is good is that Apple made Swift open source. So, that creates a lot of options. It’s just a matter of getting Hype off of Objective-C and onto Swift. Then, that might lead to support for lots of different platforms.
