The [TCP/IP] protocols were designed to allow any machine to communicate with any other machine, but these days the increasing use of [NAT], dynamic [IP] address allocation, and draconian traffic filtering is creating a class of "consumers" who can initiate connections to servers but not receive incoming connections.
This makes it harder to have peer-to-peer communcations such as voice/video chat without going through a central server, which by definition is not peer-to-peer.

-The problem with pure PeerToPeer Networks is that it can be very hard for newcomers to find peers to communicate with. Generally the solution is to have a few very well known nodes which newcomers can connect to and explore the network from, but this solution immediately privileges the few
well-known nodes and they cease to be peers of the other nodes.
