The only difference between Amazon's DRM and that of a book bought from Mobipocket is that Amazon have their own private DRM server. The actual DRM mechanism, however, is Mobipocket DRM. That's probably one of the main reasons that Amazon bought Mobipocket: to acquire their DRM technology.

In essence, you're both right. Amazon aquired the DRM scheme from Mobipocket, but they effectively "rolled their own" by altering it slightly and hosting their own server to handle the kindle DRM. It's not "standard" Mobipocket in the sense that you can't buy Mobipocket DRM content elsewhere and have it work without jumping through some hoops. The PID ranges are different, for one thing.
