I guess i should have posted this here before: https://bitbucket.org/cyborgar/web.l/src/249fe9f5c7d8/web/sockets.l That implements the RFC almost completely (there's no much implementation of the error code thingamajig because actually browsers don't even implement ping/pong correctly yet!). The implementation is in pure lisp, but it could be accelerated with a C library (actually the only thing to accelerate is the xor descrambling, could be done in an 'in-like environment). The webtest.l in the root of the repo provides a (ugly) chat server example using my web.l framework. Sorry if the code is not very elegant but I didn't devote that much time to that example. Here's the documentation of that module: https://bitbucket.org/cyborgar/web.l/wiki/Sockets Also, the spec is pretty much set in stone, at least as far as the IETF is concerned, RFC 6455 is a standards track document.
