Based on a single AZW book DLed to two different Kindle4PCs and run through a compare (by byte) there were 177 bytes that were different. I assume that the Kindle4PC's PID is embedded in there somewhere but I doubt that it is not encrypted in some manner.

The PID is in the book, but encoded with the PID itself, if I'm reading the MobiDeDRM code right. You can take the PID, and check that a book is encoded using that PID, but you can't get the PID back from the book.
What you need to do is find where Kindle4PC is storing the PID it uses. I suppose it must send this PID back to Amazon at some point, so perhaps a packet sniffer could spot this. I'd be surprised if they weren't encoding it though.
Kindle4PC must store the PID it's using somewhere on the PC's hard disk. But finding it and decoding it is more than I can manage.
