Napster, of course, was the first online service to prove the value of peer-to-peer communication, and the same idea subsequently gave us bit-torrent.   Yet, we still tend to build centralized services and servers.   This thread might be usefully carried forward only by discussion of, or references to, techniques in Perl for securing peer-to-peer designs ... not from “censorship,” but from “disclosure.”   Otherwise, it smacks only of two subjects that we need not consider here:   politics, and politics.
