MIT SchMUSE (pronounced ``shmooz'') is a concurrent, distributed, delegation-based object-oriented interactive environment with persistent storage. It is designed to run in a ``capricious'' network environment, where servers can migrate from site to site and can regularly become unavailable. Our design introduces a new form of unique identifiers called ``globally unique tickets'' that provide globally unique time/space stamps for objects and classes without being location specific. Object location is achieved by a distributed hierarchical lazy lookup mechanism that we call ``realm resolution.'' We also introduce a novel mechanism called ``message deferral'' for enhanced reliability in the face of remote delegation. We conclude with a comparison to related work and a projection of future work on MIT SchMUSE.
