1. A system comprising: a networked device configured to: automatically announce a sandbox-reachable service of the networked device to a discovery module; and a relevancy-matching server configured to match a targeted data with a primary data based on a relevancy factor associated with the user; and a client device configured to: automatically process an identification data of at least one of the networked device and the sandbox-reachable service of the networked device from the discovery module, automatically associate with the networked device through a sandboxed application of the client device communicatively coupled to the sandbox-reachable service based on the identification data, process an embedded object from the relevancy-matching server through the sandboxed application, gather the primary data through at least one of the embedded object and the sandboxed application, and communicate the primary data to the relevancy-matching server through the embedded object; wherein the client device is further configured to: constrain an executable environment in a security sandbox, execute the sandboxed application in the executable environment, and automatically establish a communication session between the sandboxed application and the sandbox-reachable service through at least one of a cross-site scripting technique, an appended header, a same origin policy exception, and an other mode of bypassing a number of access controls of the security sandbox, and wherein the relevancy-matching server is configured to match the targeted data with the primary data in a manner such that the relevancy-matching server is configured to search a storage for at least one of a matching item and a related item based on the 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 an other information associated with the user.
