Stremio is essentially a glorified torrent client with a nice UI. It runs locally on a device connected to the tv you want to stream to. It behind the scenes searches trackers and downloads from torrents of the content someone wants to watch in a netflix like UI. Someone that wasn’t technology literate wouldn’t know they were pirating content from torrents if you didn’t tell them.
A solution is that you manage the server and jellyfin and your friends/family connect to it.
While a self hosted solution like this would be nice, I would get messages everyday from friends and family frequently asking, “Can you add this movie to the server? Can you add this TV show to the server?” and they would eventually stop asking me and just pay for a streaming service if I forgot to fulfill every request. I would like to avoid having to manually add content to the server if my friends and family can just choose the content their wanting to watch themselves.
