I am surprised that Google does not publish a version of the OS which runs on VirtualBox/whatever with special hardware (not even sure what it would be) emulated. Imagine how many software folks would show off the OS running a company's internal apps. Making it easy for potential customers to sell something internally is a cheap and effective sales strategy.
