It's WEA; Windows Embedded Automotive 7 OS.
Modifying the OS is easy as s***; I've done it countless times and ran it through a self-made emulator. The problem is I and few of my contacts from over a year ago couldn't figure out the security encryption to allow the system to flash--i.e., mimic a maintenance mode. Unfortunately, I am not investing in a dummy unit to test nor would I destroy the one in my Focus or the one in my SHO.
Can it be done? Yes, but unless there is a demand--nobody is going to bother trying. It's too risky and the cost of the system to replace is not worth it.
As for the update on Syncmyride; no--that file is same across all vehicles. You can technically take the file and plug it into any car and update so long as that vehicle does not have the same update.
Now; if someone REALLY wanted to do this--the key is finding a service manager who will let you give him a reach around for a few hours with their super computer--they have the package file with the signed keys that we need to mimic all kinds of s***; including full blown re-flashes. Getting your hands on that $10k piece of hardware is unlikely unless your daddy owns a Ford shop.
