Present PowerPoint from an iPod for real

I have a 5th Generation iPod for quite some time. I mostly carried it on the bus with me to listen to music on my work commute. I used it a few times to share slideshows at parties. To do that, I dock the iPod onto a DLO HomeDock Deluxe which has outputs for S-video and RCA to connect to a TV or LCD projector. When I was asked to present a workshop at a conference last month, I decided to ditch Google Presentation and try presenting a PowerPoint slideshow through the DLO unit.
