An approach based on overlay networking can lead to a novel P2P Service Platform (PSP) that Operators can fruitfully use to compete with Web Companies. The merits and the strengths of the approach are highlighted respect to the de-perimeterization of services. Critical points of overlay networking are tackled by the integration of technologies like autonomic, virtualization, cognition and negotiation frameworks. These enhancements make the PSP proposition reliable, effective and viable. The PSP is able to support the Inner Circle concept: i.e., the ability to integrate infrastructural and permanent resources with more temporary and dynamic associated nodes. Eventually some usage scenarios are discussed for showing how a PSP and the Inner Circle concept can support and nourish new ecosystems of services.
