One of the features that the group thought would be useful to enterprise customers was the Admin API, which can allow IT administrators to remotely manage multiple Qubes machines.

Solutions to this problem can be largely divided into two groups: persistent and non-persistent workloads.

Bare metal operating systems don't tend to do so well when you run them on radically different hardware. People who do Virtual Desktop Infrastructure (VDI) for a living can explain in detail the number of possible ways this can occur, and the many, many hurdles to making it happen.

In a perfect world, the operating system can live on one disk, the application on another and the settings and data on a third.

For all intents and purposes, these break down into Op Ex and Cap Ex problems, respectively.
