Greetings,
I would like to point out to an currently active panel at the IGF in
which Zero rating is a topic of debate. I see WMF being represented
there.

A stream can be found at
http://webcast.igf2014.org.tr/live.ws5.html
(hopefully working), the title is "WS208: Net Neutrality, Zero-Rating
& Development: What’s the Data?"
