Abstract: In various example embodiments, systems and methods for mobile to mobile remote control are presented. A control request may be received at a client device from a control device. The control device and the client device may be in communication with a network. The client device may determine an authorization for the control device in response to receiving the control request. Based on the determined authorization, a data link may be established between the client device and the control device using a control device identifier. The data link may allow the exchange of information between the client device and the control device without an intermediate network node. The client device may receive a command request from the control device via the data link. The command request may be initiated by a control user of the control device.
