body: <p>Is there a good alternative to <a href="https://togetherjs.com/" rel="nofollow noreferrer">TogetherJS</a>? Its <a href="https://github.com/mozilla/togetherjs" rel="nofollow noreferrer">GitHub</a> hasn't had any activity for months, and <a href="http://www.ianbicking.org/blog/2014/09/professional-transitions.html" rel="nofollow noreferrer">this post</a> says its currently dead with its future uncertain.</p>
  
  <p>The feature most unique to TogetherJS as apposed to say, ShareJS, is the ability to see another person's cursor for use in troubleshooting/remote assistance.</p>
