title: BoilerplateJS: recommended way to handle authorization and authentication
body: <p>With <a href="http://boilerplatejs.org" rel="nofollow">BoilerplateJS</a> setup, what is the recommended way to handle authorization and authentication?</p>
  
  <p>Obviously on the server-side you'd check cookies etc to know who's logged in. But, on the client, how would you know if a user is logged in and what their username etc are?</p>
