A Node demo to run browserid with `https` module

client.coffee

image = document.getElementById 'login'

ll = (v...) ->
  console.log v

socket = io.connect window.location.hostname
socket.on 'ready', (data) ->
  ll data

image.onclick = ->
  navigator.id.get (assertion) ->
    ll 'got, sending'
    socket.emit 'assertion', assertion

page.jade

// Attention!! this shoule be compiled to `html` before running
// Tested on Fedora, Chrome
