[Building Sakai] enabling portal video chat on Sakai 10.x

[Alex Ballesté]

There are some public STUN servers if you don't want to add own one [1].

Maybe I'm wrong but I think you don't have to be scared about TURN/STUN. 
STUN is just a discovering service and TURN can be used as packages 
relay in case there isn't any viable way to connect peers directly. If 
your video session works under SSL all the data is encrypted and can 
only be unencrypted by the peers.

The only thing you could take on consideration is that if you use a TURN 
server that is under authentication, the login and password of the TURN 
connection is exposed in the browser JS stack. So the relay could be 
used by other apps.

Now I'm involved in testing ways to use dynamic sessions with TURN 
servers, where login and password credentials are generated in each call 
and can be only used for a while from the user browsers.
