Well Twofer,
In theory, if:
1. Meat cooked to proper internal temp.
2. Meat transfered to sterile packaging while surface temp was still well above 160f. No cooling allowed. Or you were smoking in a sterile environment (like an operating room or even better a NASA clean room.)
3. Packaging was absolutely air tight. Cooler wouldn't need to be sterile.
If all of the above were true, then your food would be okay after it cooled. You could probably even hold it at room temp for a period of time. However, once it was opened, the 40f-160f rules would apply for re-heating, serving and holding.
In our normal wrap and cooler method, the temps usually stay high enough to prevent problems before serving. However, since the set-up isn't sterile, meat held that way must be either eaten, refrigerated or frozen afterwards.
While a smoker is at temps above 160 bugs die. After it's cooled down, even with the door closed, there isn't one made that's airtight enough to prevent re-contamination before it's heated up again.
As far as baking vs smoking-- there are chemicals formed on smoked products that do help to retard spoilage. That's why it was and still used as a method of preservation. I would assume that the outer layer being dried in the process helps too. The less moisture around, the less the bugs like it.
