I do not believe that mechanism of delivery is a relevant feature of any of these laws. The copyright of a book is not contingent on its delivery via a binding of paper. One could argue a subscription is different than a purchase (of anything license or otherwise), but if you subscribe to a magazine you can legally resell any issues you receive. I see no reason you shouldn't be able to re-sell your Office 360 subscription. The law as decided in the Autodesk case seems to indicate that you can restrict the sale even of physical items if you assert that the items contains 'licensed' software, and state the terms of the license do not allow resale. The owner of the product could sell the physical item, but only if they could remove the 'licensed' software.
