A 4K 2 hour movie is about 40GB. Most modern smart TVs around 32GB of RAM and can probably devote about 20GB of that to buffering a stream, so yeah, that should actually be doable. While torrent-like distribution isn’t particularly good for the eyeball provider, it can be good for getting content to eyeballs under some circumstances regardless of how bad it is for said network. Unfortunately, it’s not good at knowing how bad it’s being for the network and it’s also not good at detecting the circumstances when it’s good for the end user or not. > Not to mention that it has been tried before, and didn't work then either.
