1. In a collaborative system, the components can all operate on their own whether or not they participate in the overall system. Does this represent a cost penalty to the overall system? Does it matter? Discuss from the perspective of some of the examples.
2. Collaborative systems in computing and communication usually evolve much more rapidly than those controlled by traditional regulatory bodies, and often more rapidly than those controlled by single companies. Is this necessary? Could regulatory bodies and companies adopt different practices that would make their systems as evolvable as collaborative (for example, Internet or Linux) while retaining the advantages of the traditional patterns of control?
