A process for preparing low-water ethanol from at least two streams of relatively water-rich ethanol that have a different water content by dewatering at membranes. A custom device manager may instantiate proxy audio input and output devices on the server corresponding to each real device on the client computer. In addition, the device includes guide grooves configured to receive guide pins from a fiber ribbon connector, such that when the fiber ribbon connector is attached to the device, fibers of the ribbon align with the optoelectronic device via the light transmission medium. The side bet is that a set of cards to be dealt to such hand will have a predetermined ranking.
