While this may be corrected in future code I think this method of doing GPIO certainly needs to be considered. I find it a much cleaner way to control I/O. Rather than running a multitude of wires from the BBB itself you just run one USB cable to a distant box where I/O is controlled. It also has the advantage of being usable on any platform - Windows, Mac, Linux. and easily moved between systems.
