No one is going to bet the farm on that solution. I'd be surprised if big SaaS vendors like Atlassian or DropBox go with it. But on the other hand I can see F500s (oil & gas companies, big engineering and defense firms, etc.) getting a rack or two to run their cloud-like stuff. They would not be taking much risk; this would be one system among many others they have, and it will have a life of 5 to 7 years anyway (a few million dollars and 7 years is peanuts for an oil & gas or mining company whose CapEx goes into the billions, over 50+ years horizons). I think the value is in having a cloud-like system that doesn't require an entire IT/Ops team to run.
