My fear with this is that it will be less "bullet proof" than creating a PDF slidedeck. With this I'll have to worry about getting the fontsize correct on the projector, which means I have to worry about getting a terminal set up on whichever computer I may be using for a presentation (hopefully my own, but I can't count on that) and (in the case that it isn't my own) I have to worry about networking too.<p>With a PDF slidedeck I can have the PDF on my computer, on the network, and on a flashdrive, I don't have to worry about presentation software compatibility or installing Gvim+plugins or putty, I don't have to worry about font-size, etc.<p>If I could be absolutely sure that the presentation was going to be given from my computer, then I think this would be great.
