Waldo, I think most of HIPAA is waived when you sign the FAA medical application, at least wrt the federal government sharing/disseminating between agencies. That stated, I don't know about DOD medicals and what permission they have, or who they can/will/do share with. I'd be flabbergasted, though, if data made it to FAA within, say, six months. Does DOD normally even know, officially, if any given pilot holds FAA certification, or a medical?
