I'm going to follow this discussion with keen interest, it is so important. I just did a quick Google and found this link addressing the matter of keeping insulin cool in a power outage:

Since insulin needs to be kept at a temperature below 86°F, be prepared with a method to keep it cool in the event of a prolonged power outage in hot weather. One option is to have an evaporative cooler such as a FRIO® insulin cooling wallet, which is activated by water, keeps insulin cool for two days, is reusable, and does not require ice packs or refrigeration. With reactivation, this will give you up to one month to get to a new source of insulin.

If you do not have an evaporative cooler, for the first day of a power outage, you can keep medications cool in the freezer (although you should unplug it because it will freeze your medications if power is restored). Or you can use an insulated bag or lunchbox with a cold pack, ice, or frozen food from the freezer. (Don’t place your insulin directly on a cold pack, ice, or frozen food.)

This diabetes forum thread mentions, among other things, the utility of a good thermos. Would your wife's insulin vials fit in a thermos? I have a Nissin thermos which is incredibly effective at keeping beverages piping hot or freezing cold for over 24 hours.
