title: PouchDB sync authorization?
body: <p>How do I ensure that the current user has authorization to access a CouchDB database via PouchDB?  From my experimentation, calling the new PouchDB() method with the CouchDB database name grants you access to that data.</p>
  
  <p>Setting require_valid_user to true in Futon seems to work, but the Futon modal window still pops up after authenticating the user via POST /_session.  I want to have a standard login screen (username and password) that logs the user into my application and grants access to the correct CouchDB database (via PouchDB).  I can I do this?  Any help will be greatly appreciated.</p>
