Yahoo! has already released a very similar "BrowserPlus" ... http://browserplus.yahoo.com/ http://browserplus.yahoo.com/

  They don't look that similar, since BrowserPlus doesn't appear to run arbitrary untrusted native code.

    NaCL doesn't run "arbitrary" native code; it runs a strictly controlled subset of x86, with all bblock edges verified, in a per-process environment that uses segment access controls to prevent code from overwriting code, and without access to the full system call table. It is basically a faster version of the Java applet sandbox.

      Maybe "arbitrary" wasn't the right word; my point is that it looks like BrowserPlus lets you run a small selection of native things approved by Yahoo, while NaCl lets you run whatever you want in a sandbox. Most of the restrictions of NaCl are inconsequential since they only block things that well-behaved code doesn't do anyway.

        I believe BrowserPlus will allow 3rd party plugins, though I'm not sure if they will require Yahoo approval. Also, there's already a "RubyInterpreter" plugin, though assuming it's sandboxed there's not much advantage over JavaScript, unless you prefer Ruby (JS appears to be faster than Ruby, in most cases: http://shootout.alioth.debian.org/debian/benchmark.php?test=all&lang=javascript&lang2=ruby http://shootout.alioth.debian.org/debian/benchmark.php?test=...)
