title: Real-time collaborative rich text editing
body: <p>I would like to have a real-time collaborative rich text editor for my webapp. So far i've done a LOT of research and i'm really a bit frustrated that there is nothing fitting out there.
  The thing is, that every solution out there is tightly coupled to an editor (Firepad for example uses CodeMirror/ Etherpad uses Etherpad).
  There are only two other solutions i found interesting:</p>
  
  <ul>
  <li><p>ShareJs -> works only for plain text</p></li>
  <li><p>Webstrate -> This was the MOST promising to me. It can handle DOM synchronization and therefore it can handle every contenteditable - great!</p></li>
  </ul>
  
  <p>But the problem with Webstrate is, that it is in an alpha Version. So for me it was too buggy - didn't work out. Tried to get it working for about 2 days. The text synchronization was easy. But it didn't work with iframes or other stuff.</p>
  
  <p>My claims are pretty high for a collaborative RTE - it should support:</p>
  
  <ul>
  <li><p>Images</p></li>
  <li><p>Iframes</p></li>
  <li><p>Video</p></li>
  <li><p>Text (of course)</p></li>
  </ul>
  
  <p>While i'm searching for about 3-4 days now for a solution - maybe someone of you has a hint? Would be very gentle ;)</p>
