Apparently this has been around for awhile, but I've just discovered Profcast. It appears to be a very cool application that creates video files with synchronized audio from Powerpoint or Keynote presentations. It even generates RSS feeds.
While it was created with the education market in mind, I can see this having broad usage amongst corporations, conference producers and anyone who wants to quickly and easily create enhanced podcasts.
From the site:
Only available for OS X. The full feature list is here.
