The FAA is actually quite progressive on this issue from my readings.

This would be unlike my home CAA that, when I enquired what might be the guidelines here (admittedly a couple of years ago), they said the question had never been asked, they had never thought about it and would not think about it until presented with an active case. How's that for helpful?
