At the second international GPLv3 conference in Brazil, I recorded Richard's presentation with my digital camera and have made a transcript:
http://fsfeurope.org/projects/gplv3/fisl-rms-transcript.en.html
I won't be putting my (bad) recordings online but the conference organisers will put the proper video online some time (hopefully soon).
The links to the Q&A session are broken right now but they'll be fixed when the website does another build in 100 minutes time.
At a recent GPLv3 talk I gave, an audience member said he hadn't even heard that the comment process was open to the public, so we've still got work to do spreading this information around. Hope this transcript helps.
