1. A system for independently observing and modifying activity in an actor processor, where the actor processor includes a memory, an input for receiving actor input information, an actor software state, and an actor hardware state, and where the actor processor produces a detectable aggregate physical property having a pattern, the system comprising an observer module including: a property-observing sensor for detecting and sampling the aggregate physical property of the actor processor and for generating an observation signal based on the physical property; an observer processor coupled with the property-observing sensor for receiving the observation signal, the observer processor operative to analyze the pattern of the aggregate physical property as provided via the observation signal, and to generate an observer output signal based on the analysis.
