Groupware
Groupware is a part of the platform specification that focusses on the concepts of scheduling/booking, notifications, events, tasks and projects within the context of groups, especially trust groups. A related component is group decisions, but groupware focusses more on the communications and networking aspects of groups.
Ideally the interface for this functionality would be a simple case of dragging and dropping bookable resources into a venues schedule, or visa versa, dropping a venue into a resource's schedule.
Groupware can help with a variety of applications apart from organising meetings and events, such as collaborative playlists, resource-sharing and car-pooling and can even be extended to a general physical network by combining networking concepts with trust groups.
