In one aspect, a system includes circuitry configured to establish and maintain data channels and virtual halls. Each virtual hall is associated with one of the data channels, and each virtual hall includes data and objects related to the virtual hall, where the data includes context information related to devices or users. Each virtual hall provides access to the data and objects to members of the virtual hall. Modifications to the data and objects of the virtual hall are synchronized between members of the virtual hall. |
