Stream live webcam

I'm not sure if this is the right place to post but here goes...

I'm looking to stream a live webcam on my website and have no idea where to start. I've been searching around and various things refer to Flash Media Server but this is costly and, as I will be streaming from University, it will probably be blocked on the network or take up too much bandwidth.

Does anyone know of a way to stream a webcam, without FMS or Quicktime Broadcaster etc.? Any free websites that provide this service could be possible, so long as the stream isn't available to anyone outside my website.

Thanks
