Algo Wars :- Life at the Planck Length

I read the article by Donald MacKenzie, How to Make Money in Microseconds: Algo-Sniffing ( in the LRB 19 May 2011) again recently after watching the TED video by Kevin Slavin: How algorithms shape our world
I see the Algo Wars as part of the general carnage unfettered capitalism can produce. Interesting, therefore that the cosmological speed limit (300,000 km/s less change) figures in the calculations of once and future masters of the universe. How long before the fabric of space-time constrains the ability to make money from making money? I don’t suppose the markets are going to be worried about the Plank Length for some time to come.

It did get me thinking. Perhaps we should redefine ‘thickness’ in terms of 3 Plancks with a banker's clog on!
