Hi there,
Is there a way of sharing resources between droplets in any way?
What I'm building is a core system with clients which only contain configuration, but fetch all other files from that core installation, which would be installed on a separate droplet.
Any idea and what potential security risk does it come with?
You could use SSHFS or NFS to do this:

For relying on this in production, NFS would be better than SSHFS. That said, unless you're very experienced with server administration, I actually don't recommend either. You're much better off sticking with technologies you understand and are familiar with debugging when things go wrong. For example, use a web server running on the central server and serve files to your other servers over HTTP/HTTPS.
