Simply Audiobooks looks interesting. They are applying the same model to books on CD that netflix applied to DVDs. Once my audible.com subscription is up I may have to try this, if I am not sick of listening to books by then, Even if I only need to have the books in my hands long enough to transfer them to my ipod. It's too bad that piracy fears will never have a company that will do this unlimited type of service with electronic delivery.
