Internet is nowadays a global computing platform comprising myriads of autonomous services which require targeted composition and coordination. Nature-inspired, and more specifically chemical programming models, in which a computation is seen as a set of reactions between molecules interacting freely in a solution, has emerged as a promising alternative for programming such platforms. While much works recently highlighted the versatility and expressiveness of such a model, its distributed execution is still a widely open problem. With this paper, we start the study of a distributed execution environment for chemical programs. We propose a framework based on a peer-to-peer network on top of which molecules and reactions are distributed. We e...
