Unless you running a VPN then I would not worry about it. It does kind of make a mockery out of VPN services. All those people that pay for a service believing that they are totally anonymous.I'll have a look into that media.peerconnection
I would think, it's only the likes of PRISM that will be nosing on peoples IP address's to that extent. VPN's will still have their uses when one wants to watch, TV for example, from abroad. It will also still have it's uses when the likes of citizens in a more repressed society want to get info out to the rest of the world, but that maybe a grey area depending on the country and the quality of their intelligence services.(:-})
