Video sharing has gained popularity as an application in Online Social Networks (OSNs). But, because of the limitations posed by the client/server architecture present in the OSN Video systems, its development has been impeded. The main limitations are the costs of server bandwidth, storage and the increasing number of online users and video content. The peer-assisted Video-on-Demand (VoD) technique has recently been proposed, through which, online peers help the server in the obtaining and delivery of online content. However, videos can only be shared with friends in OSNs.
