You'll notice the contract specifies a +/- 500ms slack time which would be a limiting factor in providing the data to the clients on that specific of a timing bound. Realtime constraints that are that specific can be really hard to do in bulk. You could easily group things into 500ms classes though. But 500ms is kind of an eternity in these types of things and you'll never really have someone thinking that they have a system fast enough to beat someone who started 500ms earlier.

500ms is a long time for an HFT algorithm, from what I understand. If my algo takes the Reuters feed as input (which I imagine to be a good leading indicator for trading) and I have a 500ms lead, it could be the one that bought the stock right before yours did (and enough shares to drive up the price adequately to slurp up all the margin).
