I created a stub entry for Paracopyright on Wikipedia, and it has already been greatly improved.
Paracopyright is a term that refers to an umbrella of legal protections above and beyond traditional copyright. It is also sometimes called "pseudocopyright" or "metacopyright".
Technological measures are used in combination with contractual license agreements as a substitute for copyright. As a a concept, therefore, paracopyrights are perhaps better understood as a part of contract law and not copyright law. Unfortunately, important regulations regarding consumer protection and the "freedom to contract" are not imported directly into paracopyright laws, potentially creating imbalances in the law and harmful unintended consequences.
