XMPP ejabberd customization

We need an XMPP/Erlang expert to do some simple customizations to the ejabberd source code to do the following: * Additionally call a command line shell script when encountering an offline-message * Use MD5 Challenge for login authentication * 2 other minor customizations Since the modifications we need are very minor, this job should be very easy and quick if you are already very familiar with XMPP, ejabberd and Erlang programming. Our selection process for this project will be as follows: 1. You must first demonstrate that you are very experienced with XMPP, ejabberd and Erlang programming. Evidence of previous ejabberd customization projects would be best. 2. We will sign an NDA to discuss the project details 3. We will review the bids and award the project
