couple of decades, we have seen progress at a revolutionary scale in many fields of science and technology. The invention and constant improvement of electronic chips, computers, the internet, wireless communication, nanotechnology and many other developments, have transformed most of our world and the lives of nearly every human being of our Western society. Looking ahead, the technology of the future seems even more promising. It will have features such as ubiquitousness (Weiser, 1991), ambient intelligence (Punie, 2005), terascale, nanoscale, complexity, cognition and holism (Tao, 2005). The number of systems and information appliances connected to the internet and mobile network are already being counted by the billions1, with over one trillion (1x109) operations crossing the internet every minute. As envisioned by Tao (2005) nanotechnology will soon allow us to: “…arrange
