I want to present my files - wherever they may be - to all sorts of different applications which let me interact with them in different ways.
Only some self-hosted software grants us this portability.
I’d say almost everything is already covered with Samba shares and docker bind mounts. With Samba shares the data is presented across network to my Kodi clients, the file browser on my phone, and the file browsers of all my computers. And with docker bind mounts those files are presented to any services that I want to run.
