Flickr books and prints coming soon?

There's a chance this could be be a scam leak, but word is that Flickr will soon be offering the ability to order prints of your photographs, among other cool features. What looks to be really interestings is the opportunity to order photo books covering certain categories...probably albums you've put together or specific keywords. The photos will be printed four to a page and include the descriptive information that you include on Flickr. Some real preperation would go into making a really cool book- pulling together a great set of photos, labeling, and describing them, but the final production could rediculously cool and a great way to commemorate something. The source for this leak, found here, maintains he is part of a viral teaser campaign that Flickr is innitiating to some of its power users.
