The presentation was called The Service-Oriented Web (PDF), and covers the usual topics about using the service model that comes with the Web For Free, though in a somewhat different form than I’ve used in the past. Enjoy!
BTW, sorry about the PDF. Blah. I would have expected better export-to-HTML functionality (images?!) out of OpenOffice 2.0. *shrug* At least the PDF’s textual content can be indexed by search engines.
