I think I've seen similar things on the internet. IIRC, many photo vests have (or used to have) multiple ammo-belt type loops for carrying film canisters. Nowadays they probably have slots for memory cards & batteries.
I saw something in a tokyo camera shop that looked like something a mexican bandit might consider wearing. It was a bandoleer type strap with loops to stick film canisters in that went all the way around the strap, like it was for shotgun shells or an ammunition belt. Strap 2 of those across your chest and get a sombrero. Add a military load bearing shoulder harness and belt to hold pouches that hold all your extra lenses and you'll be fixed to f$%^ with !
