title: Browser sync Rhino Environment. - Usecase
body: <p>1) I have a question regarding browser sync server side code being executed inside <a href="https://github.com/mozilla/rhino" rel="nofollow">Rhino Environment</a>.</p>
  
  <p>The client for whom I'm working for is giving me browser sync code as a npm packaged code executed using gulp.</p>
  
  <p>2) I have one more question, whether browser sync can be used as a tool to prevent the user's of this app to open multiple tabs of the same website/app that we are developing and create conflicting form changes, since browser sync will always show the same page/state across all tabs in the same browser. Or is it an overkill to implement the same using browser sync?</p>
