Camtasia is awesome. It allows you to record audio and video from your computer screen and upload it to a server for others to view …but you need a server. Now Techsmith has taken a cue from YouTube and Flicker and has come up with a beta that includes hosting (you can save the files to your hard drive as well). Enter the Jing Project. For now it is free, so give it a shot. All they ask is that you give them some feedback. It has a really cool interface and seems to work pretty well. Here is a masterful demo that I put together and uploaded in about 4 seconds.
