For FOSS4G 2007 I got roped in to doing a lightning talk. It was a fun experience and I'm glad I did get to go up on stage (and early in the conference so my talk wasn't subject to the effects of the many pubs/parties).

The slides are available on SlideShare, but it's mostly just pictures of the various projects. It's better to go directly to the bookmark list: http://del.icio.us/tags/BeyondGPS.
