Live Stream Through Flash

Ok so I am trying to learn how to set up a LIVE WEBCAM Stream through Flash.

What type of equipment do i need? Can I used a standard logitech webcam? Or do I need something more advanced? I am going for something of reasonably higher quality if at all possible.

I need the webcam to stream the feed through flash. Is there software that I can buy that does this for me automatically?

Also, can I display more than one stream?

If anyone knows ANYTHING about LIVE Streaming through a webcam to Flash, please help me out!
