The idea is that there would be two separate processes that communicate
with each other, a 32-bit GUI and a 64-bit engine. It would require some
clever design, but it would allow applications to take advantage of 64-bit
processing without being fully 64-bit.

Floating point actually does have a bit size. It applies to precision,
though, and not to maximum/minimum values. I'm not sure what, if any,
dependency float precision has on operating system or CPU/FPU support.

Well, no existing pre-10.4 app is going to run anything 64-bit without a
rewrite. I would expect to see it in Final Cut Pro first.
