Hi, Mike ...
I've e-mailed an authentic Texan to pop over here -- I hope he can answer you.
I have, however, seen him get off a ship with more than one bottle per person and I have a strong feeling that if they'd been confiscated I'd have heard about it.
It's also difficult to imagine "hooch police" and how they would operate.
