That's exactly what I'm doing because I don't (really) care about keeping what's been watched between machines. Each KODI box just runs it's own (non-MySQL) DB.

Now, it is a bit of a pain to "tweak" each machine's library to match (e.g. I have custom Movie Sets). However, I think if you set one up, export the library, and set the next one(s) up with the same NFS mounts, you can import the library and be done.

Dealing with new stuff is another matter...
