 Usenix paper:
https://www.usenix.org/system/files/conference/nsdi18/nsdi18-geng.pdf
Usenix talk:  https://www.usenix.org/conference/nsdi18/presentation/geng
   At the end of the talk the presenter mentions WAN sync between labs at
Utah, Wisconsin and Clemson "under 10 microseconds"

I'd like to see an error analysis and a complete list of prerequisites.
How does RTT/2 disappear?
