I'd love to use it if it can give me sub-second boot times in VM like hyper.sh. My intended use is to execute un-trusted JS on the server.

Having said that, you're going to get challenged on the performance (runtime) statement. In my understanding (correct me if I'm wrong), the layers between the node binary and the kernel will be the same in NodeOS and in other OSes. You'd be able to offer much better start up performance though.

hyper.sh seems to be a Docker images manager, isn't it? When running NodeOS on Docker or vagga (another LXC container mechanism) it boot instantly, and on QEmu or real hardware it doesn't spend more than 3 seconds, mostly only init the Linux kernel.
