In the examples we use a `MSS` type, which is a `map[string]string` that is `msgp` serializable.

```go
    handler := func(request *grid.MSS) (*grid.MSS, *grid.RemoteErr) {
        fmt.Println("Got request with field", request["myfield"])
        // Do something with payload
        return NewMSSWith(map[string]string{"result": "ok"}), nil
    }
	
    // Create a typed handler.
