This is just to help the people who is looking for something like mentions in ckeditor.
I modified jquery.mentionsInput to work together with ckEditor and .. It is working :)
You can see this online: http://jsfiddle.net/us6qo3Lc/ (type: @ken)
<head>
<meta charset="utf-8">
<script src="jquery-1.11.0.min.js"></script>
<script src="ckeditor.js"></script>
<link href="sample.css" rel="stylesheet">
<link href='jquery.mentionsInput.css' rel='stylesheet' type='text/css'>
<script src='underscore-min.js' type='text/javascript'></script>
<script src='autocomplete.js' type='text/javascript'></script>
</head>
<body>
<form action="sample_posteddata.php" method="post">
<textarea class="mention" cols="80" id="editor1" name="editor1" rows="10">
teste <b>teste</b> teste <em>teste</em> teste
</textarea>
<p style="overflow: hidden">
<input style="float: left" type="submit" value="Submit">
</p>
</form>
</body>
</html>
autocomplete.js is the code I created and it is in fiddle, ok ?
Well if someone with time, and knowledge, improve the code and maybe create a specific plugin with this .. I think the entire comunity will love.
I know the code is a mess .. so there are some space to improve it :)
I hope this help somebody .. thanks :)
I'm also interested in this so as a first step I added back all the comments from jquery.mentionsInput.js into your source.

I tried adding it as an embedded sample but stacksnippets.net does not like it
