Adobe has a solution called Adobe Digital Editions. My aluratek requires that in order to manage the books and upload them to the reader. I don't think that the software cares one way or the other about which ereader its organizing books for and you might be able to use it to actually place the book on the reader as I do. I think its worth a try.
