In this paper we sketch a framework supporting contract enactment within the context of virtual organisation units that are dynamically created in order to achieve a common objective by securely sharing resources, services and information. The framework is built on top of a joint extension of the policy deployment architecture for peerto- peer communities that we proposed in [1] and the contract enactment capability described in [6] that enables monitoring, mediation, arbitration and enforcement of electronic contracts in multiple, simultaneous closed collaborations. A longer-term goal is to deliver a scalable method of setting up contract enforcement and contract performance management infrastructures for interorganisational information systems that allow the ondemand creation and dynamic evolution of secure Virtual Organisations based on the ad-hoc integration of systems across Enterprise boundaries.
