Perpetual Intellectual and Mental Property Licensing Extensions
Regarding Ralph's link to the funniest April Fools Webpage of the Year (so far), Duke University's purchase of the Public Domain, a semi-serious musing:
I've often wondered to what extent education is the property of the student, the teacher or the institution? It's traditionally considered the student's property, but I think proper and rigorous application of intellectual property law could render students licensees of skills and content, much the same way that proprietary computer languages and software packages remain licensed rather than owned.
I read a story in Fantasy and Science Fiction a few years back in which singing was illegal, because it was impossible to sing without violating someone's intellectual property rights.
