One idea we've had, but not yet tried beyond some evil shell scripts, is 
to take a low quality video of the talk used for timing only. Then, use 
that to identify the slide transition timings + "live demo in progress", 
and finally generate a video from the audio + slides

Nice high quality video + audio would be better than that, and video of 
speaker with/plus slides better still! But if we can't manage that / as 
much, and if it isn't too much work, it's something to try. Let me know if 
you want the evil proof-of-concept shell script for driving ffmpeg to 
combine audio + slide as images + transition details!
