Fermilab do weekly colloquia for their staff, which are videoed and
archived on the web; some of these are quite interesting and I've sat
through a couple. Their web presentation is interesting and effective;
the video is put in a sidebar in the browser, so you can see the
speaker talking and gesturing, whilst the main "real estate" is taken
up by an HTMLed version of the presentation slides, which are
progressed along roughly in sync with the talk.

http://vmsstreamer1.fnal.gov/VMS_Site_02/Lectures/Colloquium/Lesk/vf001.htm
is Michael Lesk's talk on digitising everything, to pick an
appropriate example. Unfortunately, their implementation requires
RealPlayer, but there's no cast-iron requirement for that...
