A workgroup model for smart pushing and pulling

Our Workgroup Cache system operates as a virtual intranet, introducing a shared cache to members of the same workgroup. Users may be members of multiple workgroups at the same time. Criteria are associated with each workgroup to pull documents from an individual cache to the shared cache, or push from the shared cache to an individual cache. These criteria provide semantics of the the workgroup's tasks and interests to reduce latency for its members.
