trying to pipe net stream through http auth then back out as a net stream

example.js

var net = require('net')
var http = require('http')

var auth = require('../')

var server = net.createServer(function(socket) {
  socket.pipe(auth()).pipe(remoteConnection)
}).listen(8081)

var remoteServer = http.createServer(function(req, res) {
  console.log('remote!')
  res.end('Success')
}).listen(9009)
var remoteConnection = net.connect(9009)

index.js

var http = require('http')
var net = require('net')
var auth = require('http-auth')
var httpDuplex = require('http-duplex')
var through = require('through')

var basic = auth({
  authRealm : "Private area.",
  // username is mia, password is supergirl.
  authList : ['mia:{SHA}x511ncXd+4fOnYAotcGPFD0peYo=']
});

var server = http.createServer()
server.listen(7337)

module.exports = function() {
  function handleRequest(req, res) {
    // Apply authentication to server.
    basic.apply(req, res, function(username) {
      // Your request handling logic goes there
      httpDuplex(req, res).pipe(stream)
    })
  }

  stream = net.connect(7337, function() {
    server.once('request', handleRequest)
  })

  return stream
}
