One technical limitation is establishing the baseline signature for any copyrighted work and then what level of similarity passes or fails the new upload. What I'm trying to get at is, for instance, uploading an altered version of a piece of music with some random graphic images. How much alteration, of any form, differentiates between the copyrighted work and "my rework." We've already seen this "sampling" now. It's going to remain a problem as I can't see what "gold standard" will satisfy all parties. We could select the one that pisses everyone right off, which is usually the sign of an effective compromise.
