I read 2.2 "Election podcast and commentary (video capture and chat)", 
and derived these additional requirements:

- Ability to remember (store) permissions to use camera and microphone
- Ability to capture video (must remain even if the associated tab is 
not in focus)
- Ability to present captured video locally (I think this was already 
present in 2.1)
- Ability to capture sound (must remain even if the associated tab is 
not in focus)
- Ability to stream captured sound and video to remote peers
- Ability to receive and render audio and video streamed from remote peers
- Ability to record audio and video (both generated locally and received 
from remote peers)
