It doesn't need to be a single name. You can select the best target based on expected volatility/volume - for example around announcements. As long as both ends are synchronised ahead of time (which can be done over traditional networks).
The other chain (https://news.ycombinator.com/item?id=23903796) suggested 100 bits per second with a 5% error rate. With the (major) assumptions on that error rate and that you can modify / detect the beam in realtime that gives you plenty to work with.
Of course there is a massive difference between technically possible vs actually implementable.
Show me a backtest with a switching rate this low, on any name you can arb between the NYSE/CME/... and JPX with this 7ms advantage and I would acknowledge this is implementable if the PnL and vols justify the opportunity cost.
It’s a very cool idea but I’m skeptical that the market structure supports it.
