Plan B



''"Plan B" is also a name for a brand of Morning-after pill'' Plan B is an operating system designed to work in distributed environments where the set of available resources is different at different points in time. It's main design guidelines are: * All resources are perceived as a single abstraction, the box (instead of traditional file). Boxes are data containers that are operated using copy instead of the traditional read/write. They have type and constraints which determine how they can be used together. * The system operates on both local and remote boxes through the same protocol. Any implementor of such protocol can be used as part of a Plan B system. * Each application has its own name space and can customize it. Customization is done by defining names for boxes, as well as the order in which names should be searched. * Boxes are used by name and no descriptors are kept. Applications keep no connections to resources, they use the network to send self-contained requests. * Boxes can be advertised as they become available to be automatically bound to pre-specified names in the name spaces of applications that care about such resources. The design owes much to Plan 9 and to [http://planb.lsub.org/who/nemo/off.html Off++].
