Would be these system reimplemented in Erlang or other languages if they have dropped ejabberd?
<br><br>What's the status of <a href="http://jabber.org/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">Jabber.org</a>?<br><br>Is this string-binary problem a language problem or ejabberd implementation issue?
