Everytime I see complications with copyright I think that it should be similar to patents. Short length of time with an optional renewal if the work is valuable enough. I don't think it would be too much to ask for rights holders to be required to apply for copyright (for a small fee, let's say $5/work) and provide a central authority with a copy of their work. This would solve issues such as
1) when copyright ends for a work and a source to compare claims against
2) Orphaned works without known owners that are nearly unusable until expiration
3) Everything under the sun is copyrighted for absurd lengths of time. Does a macaroni art piece I made when I was in 1st grade need copyright for 70 years after I'm gone? I don't think so, but I understand that the newest movies need some protection.
