I'm not really sure what your issue is. You use twisted. Twisted is currently being updated to support python3. Gevent has a branch which passes tests for python 3.3: https://travis-ci.org/fantix/gevent/builds/3588293 https://travis-ci.org/fantix/gevent/builds/3588293 Is there some major library you are using that has no plans for python 3? I'm not actually seeing an issue with python 2 -> 3 transition which is what my original comment was asking about. I see a lot of negativity surrounding python 3 and talks of fracture, but no actual evidence of it.
