Hi. I am pretty new to live steaming. I am currently running a single 24 hour live stream using a webcam and the Ustream service. That is pretty much the extent of my knowledge.

I want now to set up another system in a different location. It is to be a 24 hour stream and there are to be multiple cameras (at least 2). I want the user to be able to chose which of the cameras they wish to view, and be able to easily switch back and forth between the cameras. There needs to be sound for each stream which is recorded with external mics.

So, as you can see, I know what I want! The problem is I have no idea how to go about achieving it. Can anyone offer any advice? Perhaps there is a Ustream-style service which will fulfil my requirements?

Any help greatly appreciated!
