Anything about e-books?

The problem is that I would like to upload for example 100 similar files for e-books to be purchased (there are only slight differences between them - watermarks) and all of them are to be purchased as the same product but none of them twice.

So the first person purchases this product gets A file, next person B file, third person buys the same product - is able to download C file... Never repeated. Unique links (can be set before manually) to download for each order for the same product.

No, downloads dont work like that. You could set multiple downloads to a product but they would all be available after order. You would need a modification for that, or maybe there is a way to dinamically place your watermark on the file before download, I see some discussion here: http://stackoverflow.com/questions/2913 ... -using-php

It is really much more easier to create hundreds of books with watermarks on your computer offline than to have any special module to place dynamically watermarks and create unique links that is to be used in an internet store. This would be this kind of an application that is really not easy to produce - you would require a high class professional to do it.
