Ban the current setup, where they're physically co-located in the exchange server room, and they'll just build a new space at the NOC or the CO, whichever gets them the signal faster. They don't have to be faster than everybody, or faster by a lot. Just faster than most, and just by a little.
It wouldn't take much of a transaction cost to eat up the margin from that activity.
