I can believe that:
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.
For all enthusiasts:
1. First of all is not ready for use.
2. x86 code is not portable across platforms.
3. Web means portability ... writing Active X ... sorry asm programs for web ?
4. Modules may not contain certain instruction sequences ... hmmmmm
You are still enthusiast ?
Jesus ... a new way to spread viruses ...
I hope I'm wrong ...
