Being a Vue and IClone user as well, I have my thrills with DRM. Both these outlets use encryption to enforce the EULA and to generate more revenue from users who want to use the same content in competing applications. Two sources of extra revenue - Ref: Vue Export Module and RealLusions IClone Pipeline3D Exchange. These are expensive plug-ins/add-on to the main application and there is an additional premium for content that is "exportable" in the content store. It's not unline airlines adjusting the business model by charging for luggage.
