1. A computer-implemented method for managing distribution of a data stream from a distributed computing device network, the method comprising: receiving a request for a data stream of an examination environment surrounding a user of a first remote computing device during execution of a testing routine, the request received over the distributed computing device network and during execution of the testing routine; identifying a computing device of the distributed computing device network to process the request based on at least one performance metric corresponding to a network path from the computing device to a second remote computing device; and transmitting the data stream from the identified computing device to the second remote computing device in response to the request.
