Mobile objects and the hyoctane distributed hyperdocument server

Mobile objects are programs passed between distributed information servers for execution on remote sites within a limited environment. We describe the MHEG virtual machine speciication which supports mobile code in a heterogeneous environment. MHEG VM is suitable for integration in many diierent distributed information systems, including the WWW. We brieey describe the possible integration of the MHEG VM with the HyOctane hypermedia system. We conclude this paper by discussing various issues associated with the design of robust mobile code systems.
