title: Multiple package.json files in one package
body: <p>I have a site running on php that uses Node for a few development tasks.  Currently, our team relies on puppet to install the node modules that we use for these development tasks, however, I was thinking of moving to using a package.json file in the root of the site instead.</p>
  
  <p>My problem is this:</p>
  
  <p>My php app is actually 3 separate sites that we have mixed into one (1 public facing site, 1 internal site, 1 client facing site) and its a likely scenario that some installations of the app depend on different node packages (or different versions of the same pacakge).  While I know it would be nice to split these apps apart and have each one manage its own dependencies, short of this, is there some way to have multiple package.json files in one site?</p>
  
  <p>In other words:</p>
  
  <pre><code>/package.json
  /site1/package.json
  /site2/package.json
  /site3/package.json
  </code></pre>
  
  <p>Or perhaps, is there a way to have the one package.json handle dependencies for more than one app?</p>
  
  <p>I don't know if this makes sense, let me know if I'm just way out in left field here.  Thanks!</p>
