Apple already went through this before with PowerPC -> x86. They had universal binaries, Rosetta, etc. to build off of. And they got to do it with their own hardware, which includes some special instructions intended to help with emulation.

Not to mention 68K -> PowerPC.

Rhapsody supported x86, and I think during the PowerPC era Apple kept creating x86 builds of OS X just in case. This may have helped to keep things like byte order dependencies from creeping in.
