Custom Jomsocial facebook style discussion board application

Hello, I need a custom add-on for Jomsocial that will be a clone of the old facebook discussion boards found on groups and facebook applications. It will link with the profiles from Jomsocial. People can discuss and add topics and most importantly reply to each other. When a user replies to another user that person must be notified and given a link direct to that reply. Anyone who knows how the old discussion boards on facebook worked will know what I mean. They recently removed the reply feature from facebook. This add-on will be in its own page/section. It does not need to be a Jomsocial application and does not need to replace the current group discussion board. Thanks
