If anyone finds themselves needing to write a Websockets implementation, there's an awesome protocol test suite at http://autobahn.ws/testsuite http://autobahn.ws/testsuite I wrote a C++ implementation for a side project and with the aforementioned test suite I actually found it pretty easy to get to 100% compliance. There's some ugliness in the protocol because of proxies, but it's definitely not the worst protocol in the world. The only big missing feature is compression and there's a proposal for that (you could certainly do application level compression, but I'd rather avoid writing compression code in JS).
