Or we could just.. not do that? It provides no benefit and a host of downsides

  It seems a lot more elegant/efficient/sane to me than trying to squeeze more and more racks into one building. So that's why I'm asking, as I think the benefits are clear, much better scalability, fairness (or getting as close to it as the exchange wants), cheaper (no need for fancy hardware), probably it would attract more market participants (lower barriers to entry). It's the same hypothetical "EC2 model" without the meta-game of trying to get closer to the cores the exchange runs at a given time. Can you elaborate on the downsides besides security?

    What you're trying to eliminate is just a small part of the infra arms race. But it's not even effective at that. You say one of the goals is to not have to squeeze many racks into a building, but your proposal assumes the servers placed in the racks are running at low capacity, which is completely not true. On the other hand, if you trade say GOOG, the matching engine for that is going to mainly sit in one place, how do you stuff everyone's program to run on the same server, and how do you make sure they each have fair access?
