 hellais suggested WebRTC (http://www.webrtc.org/,
 https://en.wikipedia.org/wiki/WebRTC) as a way to directly connect
 browsers behind NATs. This could be useful for the JavaScript flash proxy,
 which otherwise doesn't work at all when the censored user is behind NAT.

 We should examine WebRTC to find out at least
 # How much information it discloses to a third party. (For facilitation of
 NAT punching, for example. This was a problem with the Adobe RTMFP
 transport in the Flash-based proxy.)
 # How common it is or can be expected to become; i.e., will a censor be
 reluctant to block it wholesale.
 # What are the implications for protocol fingerprinting.
 # What browsers it is supported in.
 # How easy it is to implement and deploy.
