I've created software to generate valid ebooks from HTML/XML and auxillary files (metadata, cover artwork, etc.) The software produces books in both the ePub and MobiPocket formats and does everthing except add DRM to the book.

My ebooks will be in Norwegian.

I am aware of publisher's arrangements, such as Kindle Direct Publishing. Unfortunately, they will not publish unless the book is in one of the following languages: English, German, French, Spanish, Portuguese, Italian, or Japanese.

What options do I have to add DRM to books that I self-publish?

Assuming no free or near free option exists, if I were to purchase the necessary framework and licenses to do this myself for the ePub and MobiPocket formats, where will I get this software and what will it cost me.

I am also interested in learning about publishers that will accept books in Norwegian and will publish them on the Kindle platform with DRM.
