The app would have basic IDE for writing and debugging the python code, but the interpretation, of course, would be done in JavaScript. I'd like to avoid any client-server transactions, so all the interpretation should take place on the client side. The purpose of all this would be to create educational platform for learning the programming in python.

Some people have already made an LLVM-to-Javascript compiler, and have managed to build Python 2.7 with it.

The LLVM-to-Javascript project is called emscripten.
