I don’t use Calibre for this (but I do for epub and pdf ebooks). I use Plex and use Plexamp for my music collection. For audio books I used to have Chronicle Audiobook Player installed (which is open source, but not actively maintained) but am now trying out Listen Audiobook Player (which is not open source as a heads up). Both of those allow me to download books wherever I am.

If you have no interest in running a Plex server neither of them are suitable for you, but I just wanted to mention this solution in case you’re not dead set on using Calibre. Plex has a cost factor which may come into play (an obvious non starter for some). I have had Plex Pass for a long time so it was natural for me to use it, but might not be for you.

A Fedora Linux container on Proxmox. I have no stability issues really.

Since I can’t see any other reference to it, I want to mention I’m using openmediavault and export smb mounts for my windows computers and NFS for Linux. It is running in a VM in proxmox. Works well enough for me. It is my in house backup destination, and my Plex media files storage (plex is running in a container on the same proxmox host).

Like most and probably every other mentioned solution, accessing the nas/shared storage is not more difficult than just opening windows explorer on windows and selecting the network location, etc. I’m sure it is easy on Mac as well, but I don’t use apple products myself.

Plexamp is my primary music playback in the car commute if I’m not listening to an audio book. Love it.

Real kidnappers will not be happy about this as deepfake becomes more prevalent and calls for ransom gets ignored more and more. Do they have union that can go on strike to raise awareness about this?

Proxmox with a bunch of small dedicated lxc containers (running small Ubuntu lxcs mostly). It works for me anyway, though I don’t use any of the rr programs. My Plex lxc gets its Media files from an openmediavault NFS mount (Running in a VM instead of lxc), and I use smb file sharing for my windows desktop to access the same files. Your mileage may vary, what works for me night not be for someone else.
