"A "file Microsoft Messenger" showed it was a PPC binary (!!) How could this be? How can an AMD64 box run PPC code? Is there any type of emulation going on there?"
Rosetta, a program that translates PPC code to x86 code. Bloody slow from what I've read.

You read wrong then. It runs well enough, and I personally believe that when the new macintels come out that they will feature latest intel processors fast enough to emulate at near to today's speed. Remember that the OS is not complete yet, usually optimization is the last task done to some processes. (Vista for example)

Today at my office, someone showed me Mac OS x86.
The thing that puzzled me was: Microsoft Messenger. This guy installed the Mac version and it worked.

Other binaries showed they were both PPC and x86. Something like the "hybrid" binaries on the Motorola 68K <-> PowerPC era.
