I am looking for a way to add live video to a web site. I am teaching a history course and there are a few people that cannot attend, but want to participate in the course live. We don't want to use something like Skype for two main reasons: 1) only one person can view the video at a time and 2) there needs to be someone monitoring the computer to add people to the conference call.

What we want to do is have a page on our web site that allows the end user to click and access a streaming, live video (provided there is any live video at the time). Does anyone have any idea how to do this or what software is needed?

Any help would be appreciated.
