To-Peer (P2P) networks are self-organizing, distributed systems, with no centralized authority or infrastructure. Because of the voluntary participation, the availability of resources in a P2P system can be highly variable and unpredictable. In this paper, we use ideas from Game Theory to study the interaction

I guess if we view complementary currencies as platforms. And we are concerned with designing a currency to fulfil certain criteria, we need to consider game theoretical analysis.

Damn! I hate game theory. All that maths makes my head hurt! :-(
