  That's not how it works. Several streaming BitTorrent clients specifically request blocks in order so that you can start watching immediately.
  Not that you need a special client, it works pretty well with the standard client as well on a well seeded torrent, as blocks are generally requested more or less in order.

  Well, yes. Or you could just stream content that is guaranteed to be compatible with the device used.

  They could, and they might even have, I forget, but there is little demand for such a thing as a centralized CDN strategy works better.

  Unless network topology is somehow exposed, this isn't possible. All anybody can do is use latency, IP and ASN information as a proxy.

  Nothing is stopping a BitTorrent client from being selective about its peers. The current peer selection algorithm optimizes for throughput, not adjecency or topology.
