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.

I picked up on this through a digg link to an ars technica article. I'm sure people have seen it but since I know relatively fuck all about security but since there are people like Decius, Acidus, et al here I was wondering what people think
edit oops do the recommend then see I should have checked discuss lol
