So the new Qt Remote Objects (5.10, previewed in 5.9) looks cool, but there's not much on it. Can there be a blog post about it? I have many questions: 0. How supported is this? I've not seen anything on it. 1. What's the protocol? (firewall concerns) RPC/WebSocket/Bespoke binary/Google Protobuf? 2. How does it compare to websockets?
