If anyone here remembers this old discussion:
Named topics actually resolve ~all dynamic routing issues we’ve been discussing there. I think it should be a no-brainer to build a very simple router node (not a bridge) that plugs to a Cyphal/anything network on one side and some other Cyphal network on the other side. One particular example is linking a local network (in-vehicle or whatever) with the cloud (via Cyphal/serial over TCP as an option). I’m not planning to explore that immediately since I don’t have a use case at hand, but if anyone finds it immediately relevant, we could talk about it.
