There was the OpenGroup's Architecture Neutral Distribution Format, but I'm not sure if it was ever fully realized. Around the time that was proposed some real serious energy was put in to C compiler optimization, across the industry. It does free them up in the future, they can make bigger hardware changes and just have to supply a bitstream player for the older code. I have a difficult time envisioning the architecture changes that make tons of sense to Apple right now though, other than like swapping video on their ARM chips and stuff like that. Running iOS apps on the desktop might make a ton of sense for some of them or some sort of tweener between the iPad and Mac book.
