Intensional communities are composed of intensional programs sharing a common context, implemented using a networked context server, called the AEPD aether process daemon. The programs are written in the ISE intensional imperative scripting language, which is illustrated through versioned assignments in undergraduate classes. Using this model of intensional communities, two examples are developed: a Web-based class in which a teacher leads a student through a multidimensional page, and the programming of chatrooms.
