This disclosure relates to, among other things, systems and methods for managing the communication of messages between devices using a service system operating as a trusted intermediary. Information indicative of device location and/or orientation may be communicated to the service system, which may use the information to determine whether a transmitting device is oriented and/or otherwise pointed in the direction of an intended receiving device. The trusted service may enforce policy articulated by the receiving device in connection with the communication of a message from the transmitting device to the intended receiving device.
