1. A system comprising: a relevancy-matching server; a client device to constrain an executable environment within a security sandbox, and to execute a sandboxed application in the constrained executable environment; a networked device to generate primary data using preliminary data, the networked device executing a content identification service to identify content of media data thereon to automatically generate the preliminary data, the content identification service being at least one of: integrated with a chipset of the networked device and integrated with at least one of: a video pipeline and an audio pipeline of the networked device, the content identification service being configured to access at least one of: a frame buffer, a video buffer and an audio buffer within the networked device, the preliminary data being information associated with a user of both the client device and the networked device, and the primary data being one of: identical to the preliminary data and a converted form of the preliminary data suitable for processing through the relevancy-matching server as one of: content identification data and content identification history; and a pairing server, wherein the relevancy-matching server, the client device and the networked device are communicatively coupled to one another through a network, wherein the client device is configured to automatically establish a communication between the sandboxed application and a sandbox-reachable service of the networked device through accessing a discovery module of the pairing server after the networked device automatically announces the sandbox-reachable service thereof to the discovery module, the discovery module being a self-contained component that performs a discovery service that detects a number of devices in the network that offer the content identification service, and wherein, based on the automatically established communication between the sandboxed application and the sandbox-reachable service of the networked device, the relevancy-matching server is configured to: match the primary data with targeted data based on a relevancy factor comprising at least one of: a category of the primary data, a behavioral history of the user, a category of the sandboxed application, and other information associated with the user, search a storage for the targeted data, and communicate the targeted data to at least one of: the client device and the networked device for rendering thereon.
