Kleinrock (1996, 1998) claims that advanced wireless technologies, the Internet, Global Positioning Systems, portable and distributed computing, and so forth will realize the vision of “anytime, anywhere” computing. We can today see the first signs of this vision. For example, telework is now possible, remote organizations can be engaged in close cooperation, and people can form communities on the Internet. The world has become a “global village,” some claim (Castells, 1996; Preece, 1994), where you can interact with anybody independent of time and space.
