rgrpc (remote gRPC) is a library to trick gRPC into allowing a remote behind-the-firewall device to provide a gRPC server back to a dialable gRPC client.
This is achieved by flipping the roles of server and client. With rgrpc, the server initiates the network connection to the "client." Once communication is established, the client is able to interact with the server via gRPC like normal.
