Communicating or interacting with equals.
In networking terms PeerToPeer means that each node communications directly with other nodes. 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 prelividges the few well known nodes and they cease to be peers of the other nodes.
