Glorious!
I look forward to explore!
BTW in the case of this project it is partially funded privately by Vulcan
Inc.
c.f. http://www.projecthalo.com/
which is a necessary read to understand background to SILK.

I wonder, contra Poala, whether we are, in fact, in the midst of using some
very powerful computational and programmatic paradigms with very far
reaching implications.
No doubt, and this is fascinating, the fact that they are public is part of
this paradigm shift.
I say this with a mixture of awe and trepidation.
