I've listened to most of these a few months back and they're great. The tom Coates one contains brilliant advice for anyone creating a web app. His slides are available at http://www.plasticbag.org/archives/2006/02/my_future_of_web_apps_slides/

This page will be updated within the next few weeks with audio from the latest FOWA conference.

Thanks, I hadn't seen those slides, and they're very good.
