In my words: a computer read and write eletrical voltage, translated to binary form "0" and "1", that are grouped on bytes and words, that are translated to instructions to be executed by the computer, this is the machine code that computer understands. Someone will have to translate your graphical code generator to machine code at least. So, "there will be code".

How Digital Rights Management Works DRM: 1) attempts to protect company's paid content against the free distribution of this content between non-paying users; 2) attempts to restrict the number of devices where the DRM protected content can be used; 3) attempts to restrict the amount of activations of protected content by device; 4) is very difficult for the user to save the DRM protected content by medium or long term, due to replacement by newer devices or changing the login credentials (username and password). So: A) backup of the DRM protected content by the user is useless; B) is a hell for users to manage; C) software already exist that breaks items 1, 2 and 3 above; D) several company don't use DRM technology correctly. I think DRM is OK for rental services (short term retention without perpetual ownership). Reference: i) How Digital Rights Management Works (http://computer.howstuffworks.com/drm.htm).
