A first-modality gateway and a second-modality gateway are synchronized, with both gateways interfacing between a user and a server system. The synchronizing allows the user to use either of the first-modality gateway or the second-modality gateway at a given point in time to interface with specific information in the server system. A method includes accessing a communication sent from a first-modality gateway, and providing a synchronizing mechanism in response to accessing the communication. Another method includes receiving a request for a first-modality data from a first-modality entity, determining a second-modality data, and providing the second-modality data to a second-modality entity, where the second-modality data corresponds to the first-modality data. An article includes a first-modality interface, a second-modality interface, and a controller interface. The controller interface includes instructions that when executed by a machine result in interfacing the first-modality interface and the second-modality interface to a controller that provides synchronization.
