Lets not go down this route. I sincerely doubt legality of files has any bearing on whether DCC will support very large file transfers in the future. The fact that the DCC protocol simply isn't designed for those kinds of transfers is a far better reason. Even then, it's hardly a major change to the program and if people want to use it then it's their time wasted, so there's no specific reason it shouldn't be added at some point.
