I completely agree, that merging and syncing several video and audio
streams is a lot of work! When we do talks at local meetings, we try
to avoid this and try to capture slides and speaker at the same shot
and if possible with external microphone for a good sound quality.
In this case we don't have to do any post-production. 

I think the best case would be to capture speaker and slides in one
video stream and audio stream at the same time. So almost no
post-production is needed. But sometimes it's not possible because of
the venue.

If it's not possible to capture all in one video stream, then it maybe
possible to have two synchronous video streams: speaker and slides
(screencast or just another video capture) and audio track.
And just put them as is into media container without doing
much of post-production to avoid extra work. And everyone could select
video stream he wants. This shouldn't bring too much extra work to
organizers I think.

To have slides in PDF/ODF/TEX from speaker is always a good thing. But I see
that in a lot of cases speakers just forget to get organizers slides
afterwards and they are lost (see previous LP recordings).
Therefore I wouldn't rely on that and have at least captured slides on video.

Of course, thank all LP organizers for a lot of useful work!!!
