GhostDoc Video is up on Channel 9
If you want a quick tour through GhostDoc in less than five minutes, check out the video.
It has already been posted on Channel 9 for a couple of days, but I was a bit reluctant to link to it as the first version posted was virtually useless. My original video was recoded by the Channel 9 staff, and in the process the texts in the Visual Studio source code editor window became completely unreadable. The second version is still slightly distorted, but the texts are readable and that's what matters in the end.
