Mentioning the speed-of-light delays sort of implies that you'd have a straight shot fiber run to both exchanges (no circuitous routes, at least no more circuitous than other exchange participants - can't be behind the rest of the market, right?). I'm not sure that this is possible without working directly with someone like Hibernia Atlantic or FLAG to get a fiber splice in the middle of the ocean.... which puts this beyond the reach of the average startup and into Goldman-or-JP-morgan territory, pricewise.
