Most of the time when I give software demonstrations, I now record them. These then go into a RSS feeds. Below is a system to search these RSS feeds, currently there is about 3gb of video files online. Some good search terms are, Dreamweaver, Flash, CSS, After, Premiere.
This is a bit of a follow up on Vodcastings, Screencasting or whatever you would like to call and WebCT. I was really exicted when I saw that webCT 6 had a Public Files area, this meant to that I wouldn't have to worry about .htaccess stuff. So basically to be able to server a podcast from webCT you just up the rss feed and the media files in the public folder. Here is a screen grab of it.
The complex bit was the webCT 6 didn't like serving out .wmv files from the Public Folder, which is really wierd.
