Scalable distributed systems demand an ability to express and adapt to diverse policies of numerous distinct services. This Adaptive Policy explores the idea of providing a way for potential respondents to advertise policies and for would-be initiators to adapt to these policies to enable communication. We are designing such as system for unified messaging system to allow potential correspondents to agree on policy for exchanging messages in a flexible, predictable, and efficient manner. Our approach bases unified messaging on emerging foundations for web-based distributed computing, namely web services, and exploits the virtues of this platform to provide improved flexibility, security, and integration.
