> 2. Python's runtime is completely and utterly incapable of threading. Threading being almost essential to any decent user interface, this whole idea falls flat. While you're AFAIK correct about running Python on mobile devices, and I think anyone will admit that Python's performance has never been great, one can have a great UI without threads: use coroutines and channels instead. Fortunately, Python does have coroutines, and a channel library can be built in the fashion of Lua's channel library (https://github.com/majek/lua-channels https://github.com/majek/lua-channels). I don't know if anyone has done it yet, I'll grant, but a cursory look suggests that it's possible. The basic idea is that one would spawn a coroutine to handle each UI element, and the coroutines would send messages to one another on channels. I've no idea how fast it would be (at a guess: terrible), but it should work.
