Comment on "Things Developers Should Know About Leopard"

Blair, you can look up the carbon-dev list archives for the answer to your first paragraph. File Manager (FSRef) calls are making the 64-bit transition. It's only the UI bits (HIToolbox.framework) that aren't. This is public information.

I don't know the answer to your second (if I did, I couldn't answer due to NDA), but I can give you an educated guess based on past experience: Apple tends not to support processor upgrades, so you'll need something like XPostFacto to make that work.
