Just watched Part 1 and Part 4 from the Creative Commons Technical Summit 2008.
Part 1 mainly focused on an Introduction to ccREL
Part 4 focused on Copyright 2.0 Technologies and Registries.
Really interesting topics especially if you have an interest in the area of Creative Commons. For a more explanatory view on Copyright and its limitations, check Larry Lessig’s books and blogs at http://lessig.org.
