Response: Whatever fits into a quart-sized bag should be fine as long as each of the individual liquid/gel-containing containers inside the bag do not individually appear to exceed 3 oz.
Hmm. If I were someone who played mental "what if" games, I'd be unconvinced that this tactic improves my safety. What's to stop a bad guy from filling nine 3 oz. containers with something dangerous (cough), thereby taking 27 oz. of threat aboard?
Mind you, I'm happy that it appears I can take enough shampoo on my trips.

This is all part of the dog and pony show, for this -- ban, modified ban as practiced/to be practiced -- has no serious security benefit. But this (and the "science behind the changes") makes for good CYA and face-saving devices in the face of a need to reconciling fantasies/paranoia with realities and interests.
