title: How can I change a database for accounts by DDP on meteor?
body: <p>I have an meteor app "A" using accounts-base, accounts-ui, accounts-twitter, and accounts-weibo.</p>
  
  <p>I decided to make another meteor app "B", that is basically same as the above but especially for mobile devices.</p>
  
  <p>Are there any ways to change a database that accounts packages use on B, to A's?</p>
