They only need to point the lasers at the next bird ahead and behind, and each packet just goes down if it can, or forward or backward according to which is closer to a downlink, unless it is for a special customer. The main use for the lasers will be to offer super-low inter- and transcontinental latency to hedge funds paying thousands of times as much as a normal subscriber. They won't do anybody else but marine customers much good.
