Good interview, anaysis. Glad to see more P2P capabilities out there.
Removing the controlled/centralized servers from the equation allows a lot of flexibility. But it also means that there is no central repository of "truth" that can be used to restore state when needed.
I've found it ironique that the world beat a path from the big iron implementations to networked mini/micro solutions with a stop along the way for "client-server". We're mainly back in the client-server world again with most of our data and logic existing in the cloud, and controlled by the cloud operators.
