It might be, but you're dismissing streaming the torrent directly. If your client can use moving window to select parts—instead of just doing it randomly—you could start watching your show without waiting for 100%. This does not require support in any client other than yours (however I'd imagine you would need at least some percentage of the swarm to use similar algorithm if you want to participate when the torrent is being only just seeded). Why this is not something commonly used, outside of specific commercial clients and to aid CDN networks, is a complete mystery to me.
