Interview with David Pollak of Athena Design regarding "Dynamic DOM Rewriting", a technology they're developing using Mozilla.

Dynamic DOM rewriting "allows an HTML/XML author to tag certain DOM elements on the page as dynamic. The browser then hooks up to the server that served the page and says, "send me the deltas for these DDR tagged elements" (the method by which this happens degrades from a true server push to a periodic client poll/pull). When the elements change on the server side, the deltas between the currently displayed DOM elements and the new DOM elements are pushed back to the browser. The browser updates the DOM and redraws the changed element in the browser window."

"The benefit to web developers is that they can make pages that are dynamic, where dynamic means that data in the world can change and be reflected in the browser in real time. It's not a page refresh. It's a true stateful session where the server changes the stuff in the browser. This enables real-time stock quotes without an applet and through a firewall."
