A computer system and method for distributing, decisions in a network. The network is partitioned into multiple levels including a user interface level, a gateway level and a domain level. All attached devices in the network communicate either directly or indirectly with user interface unit. Several gateway systems are attached to the user interface level. Each gateway system has decision-making capability. Each gateway system has connected to it multiple domains. Each domain level again has a set of decision-making capabilities. When the domain level receives an input, the domain level decides whether or not it may react based upon its decision-making capabilities. The domain system may react to the input and provide the gateway with a report of the event and the domain system's reaction to it. Once the gateway system receives the event and domain system status, the gateway determines whether to react to this event. The gateway may react to this event and direct the domain system to act according to its predetermined programming. The gateway system then sends to the user interface system the event, the domain system status and the gateway system status. The status includes whether the domain or gateway systems have reacted to the event. At the user interface level, the user interface system determines whether to react to this event and then provides a notice to the user, which allows the user to input an action.
