Yeah, the two patients being treated at Emory are the least of our concerns. We will end up learning more about the disease from their treatment. Besides, our own DoD has probably had Ebola in some nondescript lab somewhere in the U.S. for years, as Ebyl alludes to in his post above.
As for Ebola becoming airborne, I don't know enough about the process of mutation to know whether that is remotely likely. I'm guessing that it *could* happen, even though it's unlikely. Then again, there are lots of diseases that could mutate in a known manner and wipe out mankind. What if human cancer became transmittable like the venereal dog cancer? Something like that would be much worse that airborne Ebola because Ebola is too hot--that is, it burns out its victims too fast for them to spread the disease very far.
