Wow, that's a lot of options! I really liked impress.js, and I'm glad to know there's an org mode "bridge" to it :)

I've only used showoff in the past (https://github.com/schacon/showoff) and it uses one or more markdown files as the source for the presentation. No need to write HTML/CSS/JS if you don't want to. It's simple and works very well.

Since it's markdown, I'm sure using org could be very possible, since org can export to markdown. Perhaps there's even a library out there that already adapts showoff to org?

Yikes! That's a whole 'nother ballgame. Even if I had something that
big, I don't think I could manage it in a single file.
