And 18F/GSA employee and open source collaborator here. =) Can definitely help answer any questions folks have.
Are the HTTP report generation/assembly tools available/open-sourced too?
I'd love to be able to use this as a starting point. Thanks.
No, the code for report generation hasn't been opened up yet, mostly because it won't work without dependancies that aren't yet public. I think that will change in the next few months; open-sourcing is definitely an intention. It will live at https://github.com/dhs-ncats when released.
