  console.log(this.id + ': voting ' + key + ' with quorum ' + voting.quorum + ' started');

  setTimeout(function () {

    this.vote(key, true);

  }.bind(this), timeout += 100);

}

function onVote(key, origin, vote) {

  console.log(this.id + ': ' + origin + ' voted: ' + JSON.stringify(vote));

function onQuorum(key, vote) {

  console.log(this.id + ': voting ' + key + ' reached quorum: ' + JSON.stringify(vote));

}

var a = new Voter();

var b = new Voter();

a.on('new', onNew);

b.on('new', onNew);

c.on('new', onNew);

a.on('vote', onVote);

b.on('vote', onVote);

c.on('vote', onVote);

a.on('quorum', onQuorum);

b.on('quorum', onQuorum);

c.on('quorum', onQuorum);

var ab = a.createStream();

var bc = b.createStream();

ab.pipe(b.createStream()).pipe(ab);

bc.pipe(c.createStream()).pipe(bc);

a.startVoting('voting', { quorum: 4, timeout: 10000 });

setTimeout(function () {

  var d = new Voter();

  var cd = c.createStream();

  cd.pipe(d.createStream()).pipe(cd);

  d.on('new', onNew);
