[ooni-dev] OONI tests of WebRTC?

[Will Scott]

Maybe not google hangouts, since it suffers from the 'google 
is blocked in china' phenomenon.

Getting a full WebRTC client will remain problematic - the 
libRTC library used by both snowflake and chrome / firefox 
is a huge hassle to link and include in a process - 
especially given the mobile considerations.

A good start might be to validate STUN and TURN 
functionality - and there are much smaller libraries for 
both of those protocols.

The other test worth having in place is seeing if a DTLS 
connection can be established - probably to a backend 
infrastructure node participating in the experiment.
