I participated in this panel with John Resig, Nake Koechley and Andrew Dupont. I did a 10 minute talk on Real World Accessibility and talked about ARIA - Accessible Rich Internet Applications and its implementation in Dojo. You can reach the full podcast and slides from John's blog post More Secrets of JavaScript Libraries.
I've included just the podcast and slides from my part of the talk below as well as a transcription.
Waiting for the podcast.....
