there could be lightweight onion routing server for nip-96 files
this lightweight server would not host files, but instead store them in database like
file_hash;download_url;decryption_key
server could host files to any clearweb host, encrypted
when requested by hash it would proxy file download and decrypt content on the fly. although decryption can also happen at client end
this routing server could be hosted on android phone with not much disk space available
