VNC to SWF sounds like the open source equilivent of a rough version of RoboDemo…. It lets you record screen activity to a shockwave file via VNC. I was unsucessful in my attempts to get this running on my OS X box, but had some fun playing around with it in Debian. With the new addon to edit the generated swf file by splicing mp3 sound or cutting/re-arranging scenes, it really does come close to the functionality of early robodemo releases – although with much more text command parameters and a lot less GUI. However, for the tech on a budget, free is always a nice price, and I can be willing to be a little kludgy at that price point!
