Also called web OS, world OS and grid OS, and related to the Global Brain theory. OS stands for operating system. The Net OS has few of the literal characteristics of a traditional operating system, but is similar in that it acts as a substrate for applications. When two information devices share information, they gain new, composite, characteristics. Their composite characteristics in some way justify considering them a new whole. So if node A talks to node B, it becomes composite node AB, and if node AB talks to node C, it becomes composite node ABC. This is true because a node has no way of telling whether an action by a neighboring node originated there or is just being passed on. Promiscuous sharing of connections among nodes means that few nodes with any connections don't have many connections, and as a result every connected device can be considered to be part of a single composite object.
