I used an Ubuntu liveCD to rsync over a backup of my iPhoto Library to the second drive on my XP machine.  I also tried out F-Spot as a replacement for iPhoto.  It is not as powerful, but it organizes files on the disk much better.  I'm frustrated with the print quality I get on my HP Photo printer under OS X.  It works great under linux and XP.  I'm transitioning to XP for my photo work.  I'm going to have to break down and buy Photoshop and Lightroom for XP.
