I would vote for client support for personal AWS keys... (same for images).
With this you just create an AWS account, run a script to set it up and then... BANG... YOUR media under YOUR control! =))
🤔 ... Maybe I should tag nostr:npub16c0nh3dnadzqpm76uctf5hqhe2lny344zsmpm6feee9p5rdxaa9q586nvr and nostr:npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s and nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z
BTW... I could definitely help with the AWS setup part/script! =)))
