Is this just for Poser files or will it work with .duf files. What happens if I need to reinstall my product and the creator is no longer available? Sorry but this really sounds like it could be a big problem for the purchaser at some point, (Daz encryption seemed bad enough although that seems to have taken quite a back seat at the moment) but this seem that it could cause all sorts of problems for the user -

''Without the plugin, you will not be able to unencrypt the file. After the file is unencrypted, what you can and can’t do with the file will be controlled based on the permissions granted by the owner.'' - what happens if the plugin is no longer availble, will the terms that the creator sets for use be availble before purchase and will it be changeable?

Sorry but I doubt very much that I would be prepared to buy anything that used this.
