Oops, sorry, hadn't seen that question.
Yes, the kind of marking done by Immateriel (Bragelonne's distributor) states (openly and visibly) at each chapter's start and end, to which customer (by email) it was sold.
That marking can be "erased", but nobody does it.
I agree that Amazon's inability to provide such markings can be due to technical reasons, but Amazon has time and again shown that it IS master of it's own technlogy. In addition,creating custom books for each buyer is easier than creating custom books for each device of each buyer, as iis done with DRMized ebooks.
