As a one person development team, it just doesn't make financial sense to program around this issue. The number of 10.3.3 users out there is relatively small in comparison to Windows, so when you run the numbers and add in a separate 10MB download, custom installer code and increased support time, it would cost a lot more for me to ship on OS X.
All Apple has to do is make the libraries an automated software update or use the same license as Sun uses and I'd ship on OS X. Until one of those things happens, I'll be shipping a Windows only product.
It's sad, since I develop on OS X and it looks so much sweeter in Aqua.
I really don't understand why Apple doesn't make this problem go away. It would cost them nothing.
