A guy in our office who is into this kind of thing looked at the object code of xcode.exe and based on that wrote a little decrypter in C in a couple of hours. I was skeptical but it amazingly seems to work on 100% of our files. I hope our customers don't figure this out! Normally I don't care about this kind of thing, but I feel a little funny posting the code, so I won't. Suffice it to say, it's doable... if you are comfortable reading Intel object code.
