Fundamental problem: either the distributed thing will be an extremely easy target for DoS attacks -- just because the service is distributed doesn&#x27;t mean the attacker need be; the attacker can be as monolithic as he wants to be -- or, it will be only superficially distributed, and actually hosted on some honking big central infrastructure.<p>Things that are smaller than Google, Amazon, or Facebook can be DoSed into total oblivion.  Abuse is the greatest unsolved problem of distributed systems.
