Hi,

Michael Klein will probably give you a more throughout answer when he gets back from vacation. But you can read up on this page: https://wiki.dlib.indiana.edu/pages/viewpage.action?pageId=513774863

Token is generated here: https://github.com/avalonmediasystem/avalon/blob/master/app/models/stream_token.rb

Basically the streaming server's app grabs the token from the streaming URL and asks Avalon's StreamAuth if this token is valid.

Pros:
+ Good JS code seperation of concerns
+ Clean plugin architecture
+ Good interface / CSS theming
+ Larger & active community
+ ~10 pull requests being merged per month

Cons:
- Naive Flash code
- Fullscreen Flash player's controls don't work well: slider not working, volume not adjustable (only on/off)
