HTML 5 Communications is part of the HTML 5 W3C standard.

Websocket
Bidirectional socket connection between server and web endpoint.
Server-Sent Events
Formalization of Comet, ie, web "push"
Cross Domain Resource Sharing
Allows web app to cross domains. Eliminates portal servers
Inter-Document Messaging
Send strings between iframes

Some use cases: XMPP/IM directly in the browser (w/o polling), real-time messaging via server-side Java JMS to Javascript, real-time event notification, access different sites in the same web app without a portal server, build collaborative tools, stream data through firewalls/proxies, create virtual private lines in the cloud, etc.
