A system and methodology for collaborating. The system and method utilize a plurality of computing appliances, each assigned a respective team designation and a respective role designation. Team control logic is responsive to a respective said team designation, to control operation of each respective said computing appliance to operate as a part of a group. Within a defined Team, the plurality of computing appliances operate having a defined set of roles. Role control logic controls operations of a respective one of the computing appliances in accordance with functionality as defined responsive to the respective said role designation for that respective one of the plurality of computing appliances. Each of the plurality of computing appliances is assigned a respective team designation and a respective role designation. Memory storage is structured as a plurality of mapped data layers, for associative storage of user input mapped by user to a respective one of the data layers. Thereafter, responsive to the respective team control logic and the role control logic, each of at least two of the plurality of computing appliances utilizes a respective associated said data layer in the memory for associated storage of annotation data representative of annotations as originated at that respective one, for the at least two of the plurality of computing appliances. Display logic selects which of the plurality of data layers are selected data layers utilized to locally generate a display presentation that is provided at each of at least two of the plurality of computing appliances.
