This looks like it has been around for a while, but I just had a listen to this five-part podcast from a Princeton University Centre for Information Technology Policy workshop from last January. I skimmed the rest, but listened twice to the full clip of the panel on the possession and ownership of data. The panel presentation itself invites a fairly rigorous but general debate about privacy and technology, but the question period gets better and better, ending with some good dialogue on issues specific to cloud computing.
Enjoy!
