Micah, as a librarian and future ipad owner (hey, Christmas is coming..), I just want to say that you and your team are the complete and utter bomb! I am probably unreasonably excited about you guys making Apple products compatible with library ebooks, but hooray! I used your instructions from http://www.bluefirereader.com/help/libraryBooks.html
to transfer a book to my iphone and success!!! I was able to open it and read it easy peasy. So now ereader purchasing library patrons have the option of Ipads as well as Sony & Nook. (Kindle, maybe someday they'll catch up.) I wish I could offer up my library for your request but I don't think they'd go for it - but if you like I could post your query to Publib, the librarian's listserv? http://lists.webjunction.org/publib/
Although I can't locate your request in this thread anymore, so maybe you don't need it. Or I just keep skimming by it. Anyway, thanks for helping make libraries stay relevant in this increasingly digital world!
