We describe an abstract architecture of adaptive applications, and indicate where we believe crucial design decisions must be made. We illustrate the use of the abstract model in the design of an image proxy, and show where studies are required in determining the appropriate design points. In particular, even though adaptation to resource constraints is generally considered a systems problem, the adaptation is visible to the user in changes in utility, and so the user must be involved in designing the application. Finally, we discuss the politics that creep in when designers change the semantics of applications.
