Does Company of Heroes CD-Key from a PC version work on a Mac?

Company of Heroes has been ported to OS X. I purchased the Windows version a while back. Anyone know if the CD-Key will work on the mac?

Please refrain from speculating whether or not it is theoretically possible. I'm looking for someone who has actually tried it in practice.

The mac version of Company of Heroes is made by a company called Aspyr which earns money by porting Windows games to the Mac. They have almost no exclusive releases, just ports. If people could just buy the Windows version of one of their games and play it on the Mac, they wouldn't earn any money, so I don't think the CD-Key from a Windows version will work on the Mac. But it wouldn't hurt to try; I'd love to be proven wrong.
