peer to peer applications

Hello Everyone, Looking for some advice. I have created an rtmfp group. In groupspec I have set the serverChannelEnabled to true. Allowing FMS to bootstrap clients automatically,  I prefer to use this rather than LAN peer discovery because it doesnt require knowledge of peerIDs. Also I use NetStream to distribute audio/video etc. and, a NetGroup to help control the group.

I have a general idea how to add peers to a group however, I'm looking to find a random peer member to bootstrap with who is a member of the same NetGroup. My question for you is how do you find a path to a peer and establish direct communication to exchange data and share audio and video?.

I'm fairly new to FMS I'm trying to understand what is the best of way of doing this.
