Seems that I can't reply to the child of my sibling comment so I'm replying here.
ACE is quite ridiculously powerful. On its primary implementation (http://c9.io), it supports multiple cursors with concurrent editing.
I've been able to use ShareJS to get concurrent editing working (see: http://plnkr.co/edit/?p=preview&s=HN4933608) but haven't had a chance to display visual cursors for all simultaneous users. I was thinking that I could get that working using Firebase.
