Since it appears that the folks who frequent the Straight Dope message boards are not going to know of an example asked for in the OP, I shall move on and not take up anymore bandwidth with this topic.
Since this topic is not allowed on Straight Dope, it should be closed.
I don’t know if it’s relevant to OP but for purpose of the U.S. Tax Code, spending even one minute of a day on or over international waters means that for the entire 24-hour day you cannot be considered “physically not present in the U.S.” for purpose of the earned income tax exemption.

Of course the topic is allowed, but since this old thread has been bumped pointlessly I’m going to close it.
