There has been considerable interest in the problems associated with real-time, multi-user interfaces for computer supported collaborative work. This paper describes our experiences in designing and implementing Virtual X, a real-time window sharing system based on the X network protocol. The Virtual X environment provides a mechanism for the collaborative use of unmodified X applications, even though these applications were originally designed to have only one user. We discuss how our approach provides a basis for future research into the human factors of shared window systems. We explore the issues that arise in implementing this system in a heterogenous environment. Finally, we explain our support for collaboration-aware software and the future of Virtual X.
