PDF and rough MP3 recording up here: http://people.debian.org/~francois/nzcs/

The video should be available from http://www.innovation.org.nz at some point.

Thank you!

With other video formats on the horizon it probably won't be too much longer before reliance upon proprietary video codecs is a thing of the past.

Cause it is on slideshare, and has audio.

It is only Free Software proponents that advocate for a world without proprietary software, which will never happen.

Until HTML5 becomes more mainstream (e.g. IE9 released and with good market-share), Flash is the best option you have for audio/video.
