Well what exactly are you trying you address?
If people are worried about the messaging growth/latency arms race, you can either do micro auctions every so often (queue up orders 100ms, match them up and fill them) or the simpler way that many exchanges are doing now is minimum quote life (aka you can't cancel your limit order for certain amount of time)
It's a potential issue in my mind for two reasons:
1. Nobody will be able to stop an algorithm-induced crisis; we can only clean up afterwards. By necessity make decisions without human intervention, and two or more algorithms that square off can and will continue to destroy segments of the market because the next set of rules entered into them drive each other crazy. I recognize that markets now have built-in trading halts in case of too precipitous a drop, but that's addressing the symptoms and not the cause.
2. Fairness. I accept that there are going to be organizations out there that can use their existing wealth to gain a significant information advantage on the rest of us, but to make that advantage literal in the form of computers with a level of connectedness that not even professional day traders can aspire to seems dangerous to me.
I can't fully articulate why and for that reason I'm willing to acknowledge that this could be a fear of a boogeyman, but I would think that granting some people special market access based on their ability to pay can only lead in a bad direction.
