Create Private Discussion Groups

In EasySocial, members can create invitation-only groups. I would like to have these groups also have a private discussion group within EasyDiscuss, to be created by the member who created the ES group, and which appears under a ED master category. The postings made in ED would then appear in the discussion stream for the group in which the member belongs. Since a member may belong to multiple groups, the EasySocial group discussion streams should only display those postings made by the member that relate to that specific group. Is this even possible to accomplish?

If my question is not clear, I can make a simple flowchart that explains the functionality.
