In the longer term, the answer is values. Peer networks are essentially all about values. Peer groups self-organize around shared interests, in the higher context of purpose. Some football fans organize into betting pools. Others organize into Super Bowl parties.
Purpose defines the expression of interest and the sense of community.
For the peer network to coalesce with the corporate network requires the foundation of shared purpose. The more that peer networks come to life, the more influential they become. They become unions of purpose. And because they are networked, they cannot be swatted aside. What you do to one person in the network, you do to the network.
