The blackout scheme is a very secondary thing. If you make interval 1 hour, then the rapid response advantage only applies to data made available in the seconds before the trading event. Rather than having a millisecond advantage on every trade, the fat pipe guys have a millisecond advantage on every 3.6 millionth trade. I think prices would be better for people not playing the low latency response game. Liquidity within an hour would probably cost a premium as you'd have to get the money from someone on the real time market.
