Ambient Networks enable co-operation between heterogeneous networks, on demand, in order to provide ubiquitous connectivity to end-users. Incorporating contexts for such networking systems in a loosely coupled fashion, though challenging, yields futuristic results. ContextWare is a model for context processing which acquires and distributes context data among interested context entities. In this paper, we initiate an implementation of ContextWare by proposing an architecture to construct and maintain a novel Pure Overlay Space with the help of a Context Dissemination Processor. It is necessary for this space/ layer to be novel and efficient for effectual dissemination of context information to enable context dissemination, and hence context-based applications, in ambient networks. For this purpose, we tend towards a context-specific overlay infrastructure for virtual interaction between context sources and requestors. Alongside the high-level discussion, this conceptualization paper is complemented with implementation details and preliminary results of a simulation study.
