Google Native Client security contest

The Google Native Client (NaCl):

"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."

A security contest is being held by Google to try and busticate their native client code. Some interesting submissions have already shown up on the issues list. Pretty impressive competition.
