1.2.  The USENET News System

   Clearly, a worthwhile reduction of the amount of these resources used
   can be achieved if articles are stored in a central database on the
   receiving host instead of in each subscriber's mailbox. The USENET
   news system provides a method of doing just this.  There is a central
   repository of the news articles in one place (customarily a spool
   directory of some sort), and a set of programs that allow a
   subscriber to select those items he wishes to read.  Indexing,
   cross-referencing, and expiration of aged messages are also provided.

As you may know p2p networks designed in such way, that they don't
require any kind of central repository (as news server in USENET).
In p2p networks you always talking with peer, and sending
events/messages directly to them not to some central storage.
The only tiny thing which p2p may require at start-up is a list of
well known peers, which can be provided by a user, or downloaded from
server which keeps track of them. Or in any other way you can provide.
