BuddyPress activity to Facebook timeline

I am busy building a BuddyPress social network. I want to create something similar to Facebook’s timeline system.

Need to do the following:
1. Set the main community activity to only show friends activities.
2. Allow members to post on their friends activity and for that post to show on that friends private activity feed.

I have spent hours searching on how to do this, found a few plugins but they are outdated. Any help would be much appreciated.
