Here are some notes on using WebRTC to stream live video to localhost.
I looked around and found a few links, but only one really works:
* phoboslab.org 
It basically uses node and ffmpeg. Works in teh Livecode native browser object. Can even set it up on a rasberry pi. Looks good.
Here are some other interesting links for the future:
* HTTP Live Streaming JavaScript player - github
* Accessing Your Webcam in HTML5 - kirupa.com
