(don't bash me too hard) Python interpreter in JavaScript

[Passiday]

Hello,

I am looking for a way how to bring Python interpreter to JavaScript, in order to provide a web-based application with python scripting capabilities. 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.

I hoped somebody already had done something like this, but I couldn't google up anything. I've found some crazy project emulating PC in JavaScript (and even running Linux on top of it), but not a python interpreter.

Of course, I could take the python source and brutally recode it in JavaScript, but that seems like awful lot of work to do. Any ideas how I should proceed with this project?
