Hi there -

So I've got a scenario where I'm looking to have Calibre run in a docker container continuously - so that it can integrate and work with a program called readarr (https://readarr.com/).

However, with the docker container approach, it is not compatible with me running the KFX Output plugin, as that has a dependency on KindlePreviewer/WINE, and that is not built into the docker container.

So this got me thinking: What if I run my Calibre DB and have the library folder all on my always-on server via the docker method, but then I set up a 2nd instance of Calibre on my Windows PC - and point it to the same DB/library? The theory being that it could allow me to handle KFX conversion on my Windows PC Calibre instance.

However, I figured I'd check on if that is even possible, as I imagine two Calibre instances pointing to the same DB/library could cause quite a mess, if the program is not set up to work that way.
