We recently launched a new website where we are exploring various emmergine technologies and standards like WebSockets. If you head on over to http://html5labs.interoperabilitybridges.com/ you can access prototypes of WebSocket and IndexDB including downloading the source. The prototypes are designed specifically for feedback and are limited from being used in a production environment.

Here's a few other posts on the new site.
