Theoretically yes, but technologically no. I can't "own" something with server-based DRM on it. DRM creates a right (or an ability) of revocation for the seller.
I 'buy' DRM-free books from O'Reilly. The lack of DRM means that O'Reilly won't ever be able to remove my ability to read those books on a new device. However, I still don't own the books, and have no second-sale rights.
