Problems as I see them are your treating the content as a read only thing. This is OK with CD's/DVD's where you do not expect to have the item changed. However once you load up 10 items with 10 different keys and you decide to save this scene which key is used to re-encrypt the objects? Or more likely with Poser and probably other software I make a scene and send it off to the Render Queue it will somehow get re-encrypted and then the other machines will have to contact some cloud based key master and hope they get through. If not then that asset will be corrupted and render as a mess. Also with the cloud based thing if you lose the internet, like I do on a frequent basis then I am just SOL when it comes to working with Poser since that is what I like to do when the internet goes out. As a final point if the Vendor encrypts the file once then there is only one lock and once it is decrypted unless you modify the file each time with a different key the object file will be the same for each person, no way to tell where the leak came from. On the other hand if you modify the object file then it is simply a matter of getting a couple of keys and looking for the changes between files and you find the tracker. Also as has been discussed over on the Smith-Micro forum the layout of an object file does have an effect on how it is treated by the program. Who is going to be responsible for issues this causes? The vendor may have a perfectly good object file and the encryption could mess it up so it does not work for some (but not all) customers.
