Great stuff! For the record: Avahi is an implementation of Zeroconf. Bonjour is another implementation from Apple. Bonjour is built into macOS. Bonjour is available for Windows too, for example it can be downloaded somewhere on apple.com. (Personally I just install Cyberduck on all Windows machines I touch - it's an open-source SFTP/FTP/block-storage client and includes Bonjour for Windows.)
