My wife suggested that perhaps Christians could set up a copyright that would expire after five years or so. As it is, copyrights today expire after 95 years, or at times, after the death of the individual copyrighter plus 70 more years. I guess her plan could work like the medical drug system in America: a new drug is copyrighted for a few years, then the market is opened for generic drugs to copy.
A friend of mine named Easten suggested another idea: creativecommons.org. It's an organization that's worked out riders to tack onto copyrights. You can choose to modify your copyright for free in several ways: to allow others to share it, or modify it, for non-commercial or even for commercial reasons. Worth checking out.
How selfish is a traditional copyright for a Christian, in light of Acts 4:32?
