Streaming? (Score 0)

Please comment because I'm not sure how many of guys are using the term "Streaming". I've worked with streaming video which is real time or buffered streaming. It's always been my understanding that torrents are downloaded in packets of data received in no consecutive order from many peers, then pieced back together, which is why you can't preview a file like you might in Kazaa or some other P2P app. So how can you "Stream" a video via the Bittorrant method of downloading information? Don't insult, I'm truly trying to learn.
