I've posted the bulk of the presentation below. (I omitted a couple of slides that were MySQL specific.) Even though it was a technical conference, I got positive feedback from the attendees and organizers that the information was useful in helping folks think about where to focus their efforts.
The slides have been posted to Box.net and are shown using their new "embedded preview" feature which is pretty cool. You can also use the short URL www.tinyurl.com/box-disr to view or download the slides in Powerpoint format.
Thanks to the folks at Lucid Imagination as well as those who gave input and feedback on the presentation.
