     So nobody cares about open-sourcing WebRTC

Except the people that would want to use it? Think of Chatroulette.

     Something that would be actually noticeable in this 
     field right now would be Microsoft that open-sources
     Skype

Noticeable yes, but useful, not really.

What would be useful is for Skype to become a standard that allows interoperability with other services and protocols, such that you could build a client, like a website, that would allow users with a GTalk account to video-call Skype users. Now that would be something.
