The dynamics of mobile systems require applications to intelligently
adapt to changes in system configurations and to their environment.
We describe a workplace in which users interact with a number of
stationary and mobile systems through the course of a day. The
relationship between systems and devices is constantly changing due to
user mobility. We present a facility for mobile application
customization called ``dynamic environment variables.'' The facility
allows flexible sharing of customization contexts, supports short
interactions with long term services, and provides efficient
notification of environment changes to applications. A sample
application built in PARC's mobile computing environment and initial
performance evaluations are described.
