Hi Benjamin, A few more details to whet your appetite (because this is a thing I've been *thinking* about, but don't have anything to show)
The biggest sticking point at the moment is getting Python on the client side. I'm aware of many attempts: * Brython (http://www.brython.info) is an in-browser implementation of Python 3 * Skulpt (http://www.skulpt.org) is another in-browser implementation of Python, but only supports Py2.6 * PyPy.js (http://pypyjs.org/demo/) uses a clever intersection of PyPy, emscripten and asm.js to *compile* CPython into JavaScript. * pyjs (http://pyjs.org) is a traditional transpiler. This project has been around for a while (longer than Django), but it's a bit behind in it's Python development - it supports most of Py 2.5, and some of Py 2.6. PyPy.js is a technically interesting approach - for certain carefully selected benchmarks, it's actually *faster* than native CPython on the same machine [1]. There's are 2 *big* buts, though - the initial download size is *huge* (20MB), and "faster" is heavily qualified by "after a JIT warmup". Brython and Skulpt now the most "useful" at the moment, but they're both 650k and 450k downloads, respectively. That's a big chunk to require as a download, especially over a mobile connection. Yes, it can be cached, but first time visitors on slow connections are going to have a big lag. pyjs takes the traditional transpiler approach, but it's also the least up to date. Another approach - and one I've experimented with - is to port a Python bytecode interpreter to Javascript. This is a lot smaller than a full Python interpreter, because you don't need to carry the parsing side of the environment to the browser - you can rely on the server side to compile the bytecode, and then ship that bytecode (which is available by introspection to the running interpreter) directly to the browser. I got something working (albeit very slow and inefficient) in around 20k. I don't know how this compares to the Ruby world - but without a highly efficient way of running Python in the browser, isomorphic web development isn't an option. However, assuming such an transpiling/execution option existed, I'd suggest that it wouldn't be developed as part of the Django project itself - it would be better suited as a third party tool - tightly integrated with Django's components, but independently developed and maintained.
