Abstract: A publication-and-subscription mechanism for team rooms, referred to as team room “channels”, through which teams are able to selectively share resources from their team rooms with non-members, and that allows selective contributions, modifications, and discussions from non-members. The team room channels operate as bidirectional information pipelines to other team rooms. The team room channels may either be broadcast to all known teams, or be published selectively to one or more designated “target” teams. The receiving team rooms may then subscribe to specific published channels as appropriate. Information items from a team's team room, such as documents, tasks, representations of team members, and/or other resources, may be added to one or more of a team's published channels. Teams can associate specific permissions with each channel, including Read, Contribute, Modify, and/or Discuss. These permissions apply to all items associated with the channel.
