Discovering peer-to-peer content using metadata streams involves capturing, for each of a plurality of devices, a content and metadata stream that describes a context of the content. The metadata streams are sent to a metadata repository contemporaneously with the capture of the content by the respective devices. Network queries of the streaming metadata are enabled via the metadata repository, and, in response to the network queries, peer-to-peer access of the content is facilitated from one or more of the devices.
