Open Stack

> ... and what is being proposed here is largely aimed at demonstrating the full breadth of OpenStack's capabilities in a compelling way that will demonstrate interoperability between OpenStack implementations and the overall capabilities of OpenStack's core capabilities.    

I think this would be a very worthwhile investment, and it would help with adoption of OpenStack by a user community who might be used to using a more traditional computing environment.  
 
And I can see how this would be useful for the science community; it could demonstrate how to rewrite some traditional workflows in a way to take advantage of the more mature capabilities of OpenStack.   

Also, sysadmins could use it to verify or benchmark different vendor OpenStack offerings.
