That’s cool, and unexpected from a corporate blog. Ma favourite e-reader setup still is the Kobo + Booklore combination. Editing a configuration file on the device I can have it connect to my Booklore library that adds my own ebooks seamlessly on top of the one I can get from the Kobo store. I haven’t setup Tailscale on it yet but it’s possible.
Do you have any more information about this?
I haven’t personally setup Tailscale yet, but looking at this it seems possible and not too difficult https://github.com/videah/kobo-tailscale
