The Chromium Blog: Web Sockets in Google Chrome.
"Starting in the Google Chrome developer channel release 18.104.22.168, Web Sockets are available and enabled by default. Web Sockets are "TCP for the Web," a next-generation bidirectional communication technology for web applications being standardized in part of Web Applications 1.0. We've implemented this feature as described in our design docs for WebKit and Chromium. The Web Sockets API enables web applications to handle bidirectional communications with server-side process in a straightforward way."
I really hope web sockets makes its way into WebKit. It's pretty exciting stuff.
Update: According to Oliver Hunt via twitter, WebSockets have been in webkit nightlies for a while now.
