If you buy the physical Windows Freehand MX box from Adobe, it comes with a Win CD and a Mac/Win CD. I've seen a bunch of these second Mac/Win CD's on eBay for the full Freehand price.
It's pretty sneaky, but I don't think it's illegal, because you are selling your own property.
I'm keeping both my CD's for keepsake. I don't have kids to feed or anything, so I don't have too big of a hole in my pocket for buying Freehand.
