IMHO for general purpose business use and internal sharing, Google Slides allows very basic animations (fades, transitions, slide-ins, etc., kinda like powerpoint) but is free and viewable to all on the web. It creates low-barrier explanatory slide decks for documentation, and I frequently use it to share complex topics with stakeholders. It works well... (but you do need to keep in mind a lot of presentation best practices though, which don't come naturally).
Nice in theory, but as far as I've seen, most home routers and devices don't utilize those, and most users don't know how to configure them, and the up/down ratio is so vast (like mine is 1000/20, a 50x difference) that it's hard to saturate the down without first maxing the up in a torrent. The exception to that is it you happen to get some phat-piped seeds who are willing to send to you super fast even if you're uploading at a trickle. But in that case, plain old HTTP would've worked better anyway.
At the end of the day the bottleneck isn't at the protocol level, but the asymmetry of home cable connections. Torrents are great when you have symmetric fiber, but very few homes do right now.
This would cripple home internet connections, where the upstream is usually a tiny fraction of the downstream bandwidth. Most of the stuff people download is created/hosted by big companies. Let them pay for bandwidth instead of individual home users (looking at you, Blizzard and other game companies who like to use torrents to distribute patches).
