That's mostly what you came in with, but talking to the framework developers is unarguably a good idea. So what frameworks? There is one great framework for asynchronous Python and that's Twisted. I'm not a Twisted guy... well not in the sense at issue here. I can tell you why Twisted is "massive": no workable alternative. An event-driven framework cannot simply call methods in a mainstream Python library because they often block for I/O. The good and gifted developers of Twisted have risen to the challenge by re-writing important libraries around their deferreds which they regard as beautiful. Our fellow scripting language programmers in the young node.js community work in a system that is event-driven from the ground up. They had the advantage of no important blocking sequential libraries to re-write. As a programming language JavaScript is grossly inferior to Python, yet the node.js guys have put out some useful code and impressive benchmarks with their bad-ass rock-star tech. https://www.youtube.com/watch?v=bzkRVzciAZg The obvious exemplars among Python frameworks are web frameworks. Developers of the most popular Python web framework, Django, famously stated their goal of making making web programming "stupidly easy". That registered with me. Django did spectacularly well, then Web2py did even better on that particular criterion. There are several-to- many other excellent Python web frameworks, and there's a clear consensus among the major players on how to handle simultaneous requests: threads. Dustin, I hope you carry on with your plan. I request, please, report back here what you find.
