As Mark mentioned, it's not on our roadmap, but if you wanted to put one together, I can suggest https://github.com/grpc/grpc/blob/master/doc/core/transport_explainer.md for an idea of what transports need to do. If the goal is a simple message-oriented transport without reference to complex flow control, I can suggest using the in-process transport as a model for how to build a transport, as it's only a few hundred lines of code and implements the transport ops required to actually have working RPCs for its context; this might make a lot of sense if your controller is memory-mapped. Alternatively, if your controller is mapped as a file, a path forward might be to make a new endpoint akin to the UDS endpoint. This would mean that you'd be speaking HTTP/2 over your HID, but again it may be a fairly simple integration.
