Ah, I see I need to write a transfer of ownership addendum :) I did not go down that road since the concern in fact as far I have gotten questions was not about transfer or purchased digital property, but just who owns what, and what one can do with it if you buy it. Though I do know that one or two companies in the past in the art field HAVE put harsh restrictions on transfer of ownership, this is not standard. Simple ownership transfer is generally easy to accomplish and respected when it happens, though it is probably (secretly) doubted and suspected by the producer of the original property, since there is no way to ensure that transfer took place and both parties are not now using the product for the price of one seat,short of issuing products with a dongle. The basic rule of thumb in transfer of ownership of electronic material such as software and art assets is this: You sell or give it away, fine. You then must delete it from your hard drive, and flat out not use it :)
