Google Native Client

Google continues to walk on the flower-bed of Microsoft, Adobe and Sun by providing regularly technologies to render it auto-suffisient and universal.
Google has just published the first development version of Google Native Client. As said by Google, "Native Client is an open-source research technology for running x86 native code in web applications, with the goal of maintaining the browser neutrality, OS portability, and safety that people expect from web apps. We've released this project at an early, research stage to get feedback from the security and broader open-source communities. We believe that Native Client technology will someday help web developers to create richer and more dynamic browser-based applications."
