Resumen
Legion is a metasystem software project at the University of Virginia in Charlottesville, Virginia. Begun in 1993, its goal is a highly usable, efficient and scalable system based on solid computing principles. When complete, Legion will provide a single, coherent virtual machine that addresses such issues as scalability, programming ease, fault tolerance, security and site autonomy. Legion is an ambitious middleware project that will provide a solid, integrated conceptual foundation on which to build applications. The vision of Legion is a system consisting of millions of hosts and billions of objects co-existing in a loose confederation united through high-speed links. Users will have the illusion of a very powerful desktop computer through which they can manipulate objects. Terminal is used here in its most liberal sense. So terminal could mean anything from a workstation to an immersive environment, such as a head-mounted display, a Cave Automatic Virtual Environment, or a portable personal digital assistant.
