Excellent. This is exactly the sort of thing I have been hoping for. Stanza on the iPhone might well be a potential market too large for the ebook sellers and Publishers to ignore. Further, I am sure that some of the Publishers would be interested in making sure that Amazon does not gain a lock on the market.
Of course, once the books are available DRM free, they are DRM free. We can buy Stanza books and convert them to other formats for our readers
