Nebula looks awesome. I say this as someone who has a slice of what it is like inside a government IT department. Is Nebula going to expand outside of NASA as well?
We already host usaspending.gov and a few other sites for non-NASA users - but our focus is on NASA scientists, researchers and engineers.
That said our work is open source, so others inside and out of government can adopt our work. For instance Rackspace has started OpenStack and it adopted Nova (our python powered compute framework).
