The online file sharing industry continues to push music publishers to place all of their content online, as iMesh CEO Elan Oren blasts them for putting up such limited content. At the same time, ebooks are attaining a rapid acceptance in local libraries even though the range of titles available is fairly limited and the business model remains the same: one electronic "copy" checked out at a time, which expires on the user's local ebook reader in two weeks. Just think of the follow-up sales that could be attained with purchase links worked in to an ebook interface when those "borrowings" expired! Moral of the story: when content technology works for your clients, embrace it aggressively, and they will follow the established relationship gladly.
