Just a thought.<p>1. Is data copyrightable, patentable or a trade secret? If not, follow the next steps.<p>2. Contact as much open-minded licensees as possible and persuade them to leak the data.<p>3.

PROFIT^W PROTEST!<p>Childish, and somehow risky (the (2) is tricky), but given enough power, the information could be made public.<p>If the departure times are copyrightable — there's something really wrong with copyright system.
