Call for international negotiation on the public domain

I also learn from the Enlightened Economist that I'm not the only one who has been arguing recently for a 'restoration of the wildlands' or space for the public domain to roam free or find safe harbours. Apparently Berkeley professor of economics, Suzanne Scotchmer, at the Global Economic Symposium, called "for international negotiation on what forms of knowledge should form a global public domain and be kept out of the international arms race towards ever-tougher (and probably ever-less enforcable) protection of IP via ludicrous patents and copyright terms."
