Internet web service delivery expectations grow every year but the underlying technology does not scale naturally to deal with greater demand for services. A simple service, once becoming popular, requires the service provider to invest in powerful hardware in order to deal with sudden spike in client interest. A standard solution involves employing a content distribution network resulting in spiralling costs with increasing load. In this paper we argue it is possible to scale web service delivery more naturally assuming clients take part in content replication. We propose a design and a prototype implementation of a P2P overlay network that shows optimistic preliminary results. An extensive simulation is provided in order to establish performance possibilities of such a network with no extra related costs or demands on hardware.
