At least check if >it's technically possible.Short answer: it's possible to write code working on Trollius (Python 2 and 3) / Tulip (Python 3.3+) / CPython 3.4 (asyncio) if you use callbacks. The core of the asyncio module (event loop and scheduler) uses callbacks. If you only uses callbacks, you can also support Twisted and Tornado frameworks.
Ok, that is a good idea.
For example, the AutobahnPython project adopted this design and thanks to that, it supports Trollius, Tulip and CPython asyncio, but also Twisted: https://github.com/tavendo/AutobahnPython So you have to find a WSGI server using callbacks instead of "yield from". It should not be hard since asyncio is young, callbacks was the only option before greenlet/eventlet, and Twisted and Tornado (which use callbacks) are still widely used.
Makes sense. Thanks for taking the time to look into it. -Angus
