Virtualized x86 in the browser doesn't get anywhere near the performance of a traditional VM that is doing kernel-level virtualization. Also, your VM images will be huge for most software packages that do anything useful.

The upside is obvious, it's idiot-proof and zero setup.

Any thoughts on a simple way to benchmark that? I suppose it'd be easy enough to time some python scripts in the hosted REPL against local execution....
