1. What if the source code that does this isn't checked in? You would need to verify that the runtime matches the source code. What if it's not spread across Google's entire codebase, and is just in one of the pieces of infrastructure that almost all of the data hits? (eg. map-reduce clusters) 2. The link out to the NSA would need to be massive as well. Would be very difficult to keep that secret. A 4G modem is not going to cut it. 3. Sure, but I imagine the NSA would be happy to put in the maintenance effort required. The data would have high ROI from their perspective.
