Alcoholics Anonymous is a real-world example of network abundance. It is based on a notion that members can help maintain their sobriety by helping others stay sober. The more members it has, the greater its capacity to help even more members. Over time, it has evolved to address other addictive problems as well. It charges no dues, takes no names, generates no transactions, so it is flies completely "under the radar" of the transactional model of health care.
