Three months ago, CodeWeavers CEO Jeremy White offered a challenge to another CEO -- the nation's chief executive, George W. Bush. If the president achieved one of White's six "Lame Duck" goals during the twilight of his 2nd term, White would make Windows-API enabler & WINE GUICrossOver free to customers for one day. Some considered White's proposal a great motivational tool for GWB; others found it smug, partisan and kind of a goofy way to promote the company's products, but in any event none of his six challenges seemed to be on the path to achievement, so that's where the story should have ended. CrossOver is a fine way to run Windows apps on your Mac, but as a force for political change, not so much.

Then a funny thing happened on the way to January 20th: due to global economic conditions and through no fault of the president, the price of crude oil dropped precipitously and the cost of gasoline moved in parallel... bringing the average price per gallon in Minneapolis down to the target $2.79 level called for in White's goal #1.
