This opens a world of possibilities. I'm extremely impressed.

"This opens a world of possibilities."

Does it? I'm extremely worried if anyone plans on using this for something mainstream, as impressive as it is.

Why be worried? Is creating a virtual machine from a browser any more or less of a cause for concern than "normal" ways of starting virtual machines?

As per possibilities, the traditional ways of starting machines are (roughly): 1) bare metal, 2) subsets of bare metal, or 3) using relatively dedicated software to start virtual machines. Starting a virtual machine from a web browser is new way of starting virtual machines, with a very common denominator.

I imagine an early application will be more extensive fuzz testing of the Javascript sandbox security implementation. This will hopefully lead to better sandboxes. Unfortunately it's also likely to lead to more undisclosed zero day exploits being sold to intelligence agencies and crooks.

Doubtful. If you wanted to test Javascript security you'd do it by writing Javascript code directly, not by writing 386 machine code which runs in an emulated machine implemented in Javascript.
