> They have ( maybe recently? ) started to create this Gateway Protocol https://docs.openclaw.ai/gateway/protocol to connect the stuff together.

That's a communication protocol between openclaw server and clients authenticated to that server though, it's not a communication protocol between different openclaw servers, is it? More like defining a HTTP+JSON protocol between a web server and a browser side client application. It's not a "protocol defining how to interact with distributed nodes", again, unless I misunderstand something.
