We introduce the Notification Service Transfer Protocol (NSTP), which provides a simple, common service for sharing state in synchronous multi-user applications. A Notification Server provides items of shared state to a collection of clients and notifies the clients whenever one of the items changes. The division between client and server in this system is unusual; the centralized state is uninterpreted by the server. Instead, the responsibility for semantics and processing falls on the
more » ... which collude to implement the application. After describing NSTP, we differentiate it from other systems in terms of the four design principles that have guided its development.
