In 2012 it turns out there was a great deal of interest in libwebsockets, the lightweight, portable C websockets library, that I did not entirely stay on top of due to work commitments. In order to take care of that better going on I have created a trac and mailing list at http://libwebsockets.org/ where support and cooperation for improvements should be easier.
Recently libwebsockets has absorbed almost all of the patch delta in Dave Galeano's github branch and added new features like configurable logging; the approach to autotools has also been fixed so it is much more compatible. If you're interested in libwebsockets please consider visiting http://libwebsockets.org/ and joining in. Edit: http://git.libwebsockets.org and git://git.libwebsockets.org are both working now. http://git.warmcat.com/cgi-bin/cgit/libwebsockets/is a symlink of the same repo so you can use either.
