Does anyone know if fetch.io or put.io caches requests across accounts? It seems like a pretty obvious optimization, but neither services advertises this ability. Find appropriate torrent, it already exists on the server, start streaming immediately. With enough users it would be like a shady version of Netflix. At least until the MPAA catches on and floods them with DMCA requests.
