I wonder if a blossom server would be suitable.

I know that you can configure most clients to post to multiple blossom servers, but with 3+TB youd probably have to pay a good chunk for anybody else to host it
Ive been thinking of making a POC fork of amethyst with pears.com support for torrent-like media hosting, but it would require a new NIP and would probably be way more of a project than I anticipate lol
I think that could be pretty cool.
I have thought in the past that it would be an interesting business to sell a small piece of hardware that was dedicated to hosting your own nostr relay and media, with a custom GUI to manage the relay for monetisation, aimed at creators and journalists.
