Nobody is going to hand over $200 without at least some of those items listed above. So it just seems a bit strange to even want to release it.
I'm just saying you should slow down a little bit, take a look at http://www.rubymotion.com/ for example. It's the same sort of thing, Ruby for iOS. They provide both examples, publicly available documentation, they even have a way to try it out yourself and see what it looks like.
This seems a little awkward. A sample project setup to build for both platforms would be useful to see.
For some types of applications, the native UI boilerplate would probably be minimal, but for apps with complex UIs, this might add a lot of dev overhead.
Don't get me wrong though, this looks cool!!
