Here's my OSCON presentation [ODP, PDF]. I was part of a 15-project series of lightning talks. My talk and the whole session went quite well, but the audience wasn't as large as I would have wished. Likely this is because things came together a bit late, so there wasn't enough time to publicize it properly. It was definitely the coolest thing happening at that time slot, but it was the end of the day so people were tired out.
Alastair, you were wanting something about what's going on with Gentoo. Here 'tis.
Joe "Zonker" Brockmeier published a Newsforge article about OSCON that briefly mentions my talk.
