I don't know if you can create drivers or something to make it work with Skype or some other video chat program, but there are some apps to stream live video onto the web.
UStream - This application has the shortest delay (about 3 seconds for me), but I don't believe you can share the video stream privately.
Qik - This application has a pretty long delay (about 30-40 seconds for me), but you can send a private link to someone and invite them to view the video.
Btw, if anyone knows how to have a private video with UStream, please let me know!
