title: Share resources across different amd modules
body: <p>I'm currently developing a new web application.<br></p>
  
  <p>This is the first time I'm using requirejs with AMD modules.<br></p>
  
  <p>It's not that easy to get used to that new paradigm that there are - as I understand it - no variables in the global namespace.<br></p>
  
  <p>In previous web applications I always had one variable in the global namespace which I could use to share several resources across different modules.<br></p>
  
  <p>Now with requirejs AMD modules, I use backbone.js and jquery (both amd versions - jquery 1.7.1 and backbone.js 0.5.3-optamd3).<br></p>
  
  <p>Somewhere in my application I fetch a backbone.js module from the server (user object). I would like to have access to this module from different AMD modules. I also want to have an application wide event object.<br></p>
  
  <p>Could you tell me: what is the right way in requirejs AMD to share resources across different modules?<br></p>
