Yeah, I'm not aware of any "normal" libraries going the CDL route, all the digital lending I've seen takes the form of licensing ebooks and using Overdrive or something like it, and those ebooks are totally separate from the physical holdings (and they're also, from the library's perspective, priced totally differently, with significant restrictions on usage and total number of lendings and things like that).
