Oh, I was hoping this would be something built more directly over Ethernet, rather than on top of UDP/IP (if I'm understanding the layer diagram correctly).
I've been working with Ethernet devices a lot lately, using the network as a communication bus, essentially. I find that there's a lot of complexity that we simply don't need: ARP, DHCP, DNS... So many points of failure. We know all the devices on our LAN and their unique MAC addresses, and could do everything we need to addressing-wise at Layer 2. But everything's built on Layer 3 and up, so we're effectively working backward to map devices to IP addresses and vice versa. It's unsatisfying.
