I've read a little about the AGE85 project in the US, it sounds like you are involved. Can you give us a bit more information? Other than US insistance on using corn as a base it may be the future and more news would be welcome.

They are/have been testing the product in aircraft, so they should be able to answer you concerns about it's compatibility with aircraft systems in general. I expect your safety concerns are more about its practicality with no infrasctucture, like Madame Daimler who bought a tank of petrol from a chemist to get home off the first cross-country car ride. I can see that if you are flying from X to Y there will be situations where you are faced with the choice of diverting to Z (ethanol free) or bending your own standards/regulations to get to Y and your next tank of motion lotion. How safe that is is entirely up to you
