As you noted reading from the original post in a followup... I'm  
thinking
it critical that the recording / broadcast process be external to the
presenter's system, so we don't have to rely on a lot of unknown
and unforeseeable quantities.    It's already problematic enough just
dealing with the VGA projector connection variables like having the
system outputting a usable screen resolution and scan rate in a
standard 4x3 aspect ratio and having a laptop and OS that supports
dual display routing (with a user that knows where to turn that on)
etc.

This actually sounds very much closer to my ideal delivery form.
I don't care about the pixieo part so much - wasted bandwidth
at any size in my book -- but if you could tie the screen info to
the time line of your (ogg/mp3) audio track (think old school
film strip), then you'd have a very compact delivery mechanism
with high quality visuals.  Scaling the audio encoding quality to
single channel voice at 48kbps you get a 90 minute presentation
with full resolution screen shots into a file of 40 megabyte or less.

Once you have visuals, text and language, you've got the
overwhelming bulk of the communication.  Motion video is
mostly pocket fluff at that point.
