Still waiting for the audio, so the video will be a bit later.
In the meantime I've posted the slides with slideshare. For some reason the encoding they use has messed up a few slides and the transcript is just gobbledygook and I can't seem to find a way of removing it.
I note that they use S3 - and for some reason this crashed my preview in blogger - oh well. Still at least it's a fairly easy way of getting slides up, though not quite as easy as video.
