TL;DR http, properly implemented, supports a ton more stuff than even many “web developers” are aware of, like… range requests, which are exactly what you’d think they’d be.
iirc Jigsaw was used to develop and validate the WebDAV protocols and XQUERY which at the time I remember thinking XQUERY was sure to be the future as implementations of advanced data management and manipulation and query and distribution and declaration looked to be what the whole point of webservers were for. The incredible distractions caused by "rich media" as opposed to multimedia as it was understood then, are really worth thinking about. Saying that, however, the BBC is doing excellent work on restoring the balance of necessary powers to the network standards engineers https://www.bbc.co.uk/sounds/help/questions/about-bbc-sounds...

Connecting this to HTTP range requests, the edited video feed can consist of a list of the exact byte ranges that the clients need to download and play. Found this description of how Akamai uses range requests to serve low-latency streams: https://blogs.akamai.com/2020/11/using-ll-hls-with-byte-rang...
frankly I think that unless we do things like this, the Internet is simply going to become a closed shop to anyone not wielding enterprise budgets and legal department capabilities.
