Yup, this is work in progress. The first part of this is Jitsu, which is a DNS server that can spin up Unikernels on an incoming request.

What Hacker News says
3 sourcesThere's a paper we'll be presenting at NSDI next year on Jitsu, so there'll be more to read about soon. The repo is at https://github.com/MagnusS/jitsu
Regarding the scaling, it's definitely something we're keen to do. For example, we should be able to create hyper-elastic clouds by rapidly spinning up and culling unikernel VMs in response to demand. e.g a simple scenario might be me serving my personal blog from a cubieboard but if a post ends up on HN, then my infrastructure should automatically scale with the demand -- complete with load balancers etc and elsewhere on a public cloud provider. As demand falls, my footprint shrinks back into just the one VM on the cubieboard.
I'm sure these ideas aren't new but unikernels should make them easier to realise.
