I've worked at trading firms where the "reference data master" file is usually a big json or equivalent.
To get the file out to 100s or 1000s of machine they would often use private bittorent to distribute the file out.
I've seen this used for distributing container images in networks with awkward network topologies (e.g. a lot of bandwidth within a site or sub-site but limited bandwidth to central registries)
Same here. Inspired by both, I used to delivery videos over torrent to in door machines since at that time, there's no CDNs (or it was difficult to get one).
As a private network, they have the option of multicast.
When I retire and/or get "F You" money, I'm going to publicly tell a story about multicast, bittorrent and "not invented here" syndrome.
