What does it mean to sell an eBook? Lets say I went and actually bought an eBook from Amazon. How would I sell my copy of the eBook to you? Doesn't it have to be bound to HW to actually sell it (or DRM'ed). It seems like prohibiting transfer is the only reasonable solution, unless DRM is used.
But how do I give you an eBook and relinquish my ownership rights? It seems like it relies upon me voluntarily deleting the book. Just from a pragmatic perspective, is that really a feasible plan?
