The other thing is from a speaker's perspective, I can see some value in having speaker-specific stuff somehow bundled into the app. Thinking kind of big here, but if there was some kind of login element, you could offer schedule items specific to the person using the app (e.g. meet up for technical check backstage, etc.).
