Peer network

[callumacrae]

Hey!

I've been thinking about how to solve the problem of a peer-to-peer group chat between a significant number of users without overloading the network: if I'm in a room with 1000 people, I don't want my browser to open 999 connections.

If I'm understanding the code correctly, does friends just open a connection to every other peer like I just described?

friends-swarm/swarm.js

Lines 100 to 120 in 02bc0e1

	sw.on('peer', function (p, id) {
	var stream = log.replicate({live: true})
	log.peers.push(p)
	p.on('close', function () {
	var i = log.peers.indexOf(p)
	if (i > -1) log.peers.splice(i, 1)
	})
	swarm.emit('peer', p, name, id, stream)
	stream.on('push', function () {
	swarm.emit('push', name)
	})
	stream.on('pull', function () {
	swarm.emit('pull', name)
	})
	p.pipe(stream).pipe(p)
	})

This feels like it's going to be a super interesting problem to solve: have any of you thought about it before or know anything about the topic?

Its possible to pass maxPeers to limit the number of connections. Here is where friends does it.

maxPeers is an option exposed by webrtc-swarm.

What happens when the number of users exceeds 20?
