In 
<http://datatracker.ietf.org/doc/draft-ietf-rtcweb-use-cases-and-requirements/> 
there is a use case that uses two cameras: Hockey game viewer. There one 
camera is used to show the game, the other a view of a person attending 
the match (and participating in an on-line discussion about the game).

I guess that if the web app gets access to both cameras switching views 
would be simple to implement. You could be lazy and transmit both videos 
all the time but select which one is displayed in the video element, or 
you could enable/disable tracks or add/remove streams at the sending 
side if you like to save transmission.
