Share library's between installs

I have two Volumio installs. One in my office and another in the kitchen. I was wondering if there is anyway to share the database/library between them so they can sync things like playlists?

I have had a search on Google but most of what I found was about multiroom audio (i.e. playing simultaneously on several devices) I don’t need that, all I want is for each install to be able to use each others data. It could well be that I was using the wrong search terms though!! :smiley:
