There will be a debate in NYC this Thursday evening (Nov. 17) at 7 p.m. on Google Print. Larry Lessig's blog gives the details. He also notes today that the debate will be streamed over the Internet at this site (note that there is nothing there now). I hoping that the debate is archived on the Internet, so it can be watched later (for those of us who will not be glued to our computers Thursday night).
BTW I hadn't posted this earlier, because it was "just" an event in NYC, but now that it's going to be webcasted...!
