I'll point out that React is itself on version 0.14. Version numbers don't mean much.

Yes, it was 0.14 at the time I believe, though that version number doesn't really mean that much. Would you have been more comfortable with 1.0.0? That's what the core library was at. Anyway, I should have realised there were some essential components missing and the JS interop would be a major road-block for this application.

To clarify further: I normally work as a firmware/electronics engineer so this was a bit of an experiment all around. I didn't charge my normal rates either.
