Moving from MOOs to Multi-User Applications

This paper provides a brief description of the work we have done on the V-Worlds project, a system that facilitates the creation of multi-user applications and environments. We have taken concepts originally found in object oriented Multi-User Dungeons (MOOs) and extended them to deal with more general multi-user and in particular multi-media applications. We present reasons behind the architectural decisions of the platform and show that it has been used successfully for a wide range of examples.
