Not a worry. We don't have eBook watermarking/stamping yet, so every customer will get the same exact eBook. That said, it's relatively easy to implement this specific feature (pretty sure I've got the relevant code from our old codebase somewhere) if/when a seller requests it. It's mostly either downloadable goods, or serial-based products, but we launched just last week so I anticipate the type of popular product types will change as we grow.
