From TFA, it seems this system is aimed at understanding brain damage and not at preventing interoperative awareness. Unfortunately the article doesn't give enough detail to know if the new tool is also based on EEG (I can't access the original study through the paywall). But, if it is, and if it gives a better sense of what patients are aware of, maybe it will have some use in the operating room as well.
In the Iraq case described in the article, there seemed to be some concern (misguided in my view) that hooking up online, posting nudies on CL, etc., is prejudicial to the "good order and discipline in the armed forces." While agreed that the Secret Service exhibited very poor discipline in soliciting prostitutes in Colombia, I'm not sure I see how a "casual encounter" between two soldiers in Baghdad undermines good order or discipline.
