Is it possible to limit/whitelist the gen_server’s that nodes can communicate with? Particularly for limiting code replacement / system calls. With message forwarding features it seems plausible to do. That’d be great for siloing data systems but still utilize an Erlang distribution layer, especially in systems with GPDR or HIPAA requirements. Or perhaps IoT applications.
