I have always been led to believe its the uploading of files that is illegal, if you look round the net there are loads of places to download files of all sorts from.
There is also another loop hole which means you can download a rar file but it only becomes illegal if you extract the content. There is also encryption systems available which is going to make the whole process difficult to implement. Then there are the darknets that actually use high amounts of different users pc's to download parts of a file so no complete part is downloaded by any single user. There are also very competent hackers about that can readily use someone elses pc remotely to get the files they want with no come back to themselves. I personally think this scheme is going to be virtually unworkable, ie too much time to break things down to catch people unless they are using torrents
