Testing theories through practice is an important approach to teaching, especially in scientific and technical curricula. Often, lack of resources and logistics problems makes practice impossible. During these last years, several attempts to find an alternative to in-laboratory experiments have been proposed from many researchers. In this paper we present our approach to remote laboratories challenge. We outline the model we have created and the prototype we have implemented and validated. Finally, we propose a grid-oriented vision of our work that could be an effective solution to support experimental activity in e-learning efforts among a scattered community of users.
