You're going to need a piece of software that will take your cam and put it online. I did a quick search and found a program by Cambrosia
, which you can try for 30 days to see if it is something you'd be interested in; it's the Station Transmitter. There is also EZCast
by Webcam 1-2-3, which also has a free trial.
You can also do it with Windows Media Coder, with a How-To using this site
I also found a site that is similar to YouTube, but with live video. It's called Ustream.tv
, which might or might not be something you are interested in, but it looked interesting and thought it might be something you'd want to look into.
I hope this helps and good luck!
