I seriously doubt Roku would ever add such functionality. I only know of one device that supports that functionality, and that's the Nvidia Shield. Some of the other, lower cost Android based devices might also support accessing the drive remotely. But it doesn't fit within the Roku design plan for their devices. It also opens a potential security hole for someone to access the Roku internal file structure and possibly mess with the operating system, potentially bricking the entire device.
