Live Labs Web Sandbox

Earlier today we launched a technology preview for Web Sandbox, a project aimed at securing Web 2.0. The Sandbox applies techniques from programming languages to inject an interception layer that in effect virtualizes the execution of untrusted code in the browser. Among other interesting things the interception layer also gives us an opportunity to normalize the DOM API exposed to developers. Take it for a spin in your favorite browser--4 popular browsers shown below--and come the session Live Labs Web Sandbox: Securing Mash-ups, Site Extensibility, and Gadgets that Scott Isaacs and myself will run next week at PDC2008.
