In theory indeed. Marmot is a total mess if you want to fetch by kind etc... You need the whole group state all the time etc.... Maybe sth can be done similar to how they do blossom, but I'm to stupid for that. Nip-17 is not an option for me. Too many attack vectors. If encrypting your notes with Nip-44, I think it can be a good enough solution for mil content type groups too, I think. With a stroooooong incentive to have your own server obviously.
