I'm currently testing: FlippingBook - software for creating online publications, magazines, photo albums and flip books with the real page turning effect. Windows only unfortunately but it will do in our case I think.
I'm in the same boat as a printer wanting to supply the flip book to customers. The above does not have the linking feature built into it but I've found that if the PDF already has links in it or if I create links in Acrobat in the PDF that they will be clickable links in the Flip Book.
