Question: Wouldn't it be more cost effective to tweak a diesel to burn Jet A than to crank up a whole production facility to supply aviation grade diesel?

Yup, that was what I was trying to say. There really isn't much tweaking necessary, I've heard of people who work at airports filling up their diesel pick-ups with jet fuel. I was just thinking that if diesels really do catch on, there may be a time when the production demand warrants producing a less expensive avdiesel (would be less refined than jet fuel) that would costs less. But honestly, I don't think that will ever happen.
Using jet fuel in a diesel engine is pretty much the same as using 91 octane mogas in a 87 mogas car, or using avgas in a car. It is a more refined product, but does not make your engine more efficient or more powerful.
