This paper explores a very simple idea: what can be achieved by using the principles and the technologies of the Web Platform1 when they are applied to Ambient Computing? To answer this question we will present an experience that addresses some of the problems of Ambient Computing by making use of the technologies and the common practices of today’s Web Platform. The aim is to provide an architecture that tries to lower the deployment costs while guaranteeing accessibility, interoperability and extendibility. Key words: Web Platform, Ambient Computing, Interoperability
