Okay, I created an account at openhub. They do have an openinkpot project (google "summer of code" 2008) but it has ZERO lines of source code in it, and ZERO contributors. How can they estimate so many manhours and so much value to so little code? Oh, wait. That estimate is for a different openinkpot project with 9.8M Lines of code.
Meh. It looks like ALL 64 dowload locations are on the defunct openinkpot.org domain. Or something... Do they actually ARCHIVE stuff at codehub, or just links to external repositories?
And archive.org just has teasing snippets of git.openinkpot.org:
