I did the math on this. It probably wouldn't be good for hft. The highly profitable hft is done on the floor of the nyse. There's some from Boston but they typically use directed radio instead of fiber-optic. Satellites will be even slower, but maybe cheaper if you're sending date from California or Australia. But it's still probably cheaper (and more profitable) to put a machine on the floor or even just in NYC.

I'm not sure why hft would be a major pitch. These people fight for floor space at the nyse because that much latency matters.
