The future of Free Calling

Interesting post on the future of Free Calling by Andy Abramson.  With iNum numbers people would be free to call each other, regardless of platform. iNum numbers, federations and WebRTC can help to connect these islands of VoIP, even if they are continental in proportion. IP Communications providers like Skype, Google, Viber and Facebook/What’s App need to connect with each other to make calling really “free” . What do you think?
