This is very interesting! It will be even more interesting to see if it can be compiled to run on my OS. This is exatly the kind of application I have been looking for. ESXi is too big :)

As a side note, I personally convinced that today OSes are an overkill for cloud-based number crunching (the prime case for zerovm) wasting resources. I am looking forward for future a lot lighter 'cloudware'. Think 'opencompute' approach for OSes. zerovm is being a humble experiment here.
