If we're going to talk about a hypothetical internet where Google and Facebook have no ability to siphon all our data, we might as well propose IPv6 for everyone and NAT for no one. Then we could have high quality peer to peer services for things like instant messaging and email and social networking. We'd have the best of both worlds.

Oh, and ISPs would be regulated as utilities so their services would be dumb pipes with high bandwidth, low latency, and no caps or throttling of any kind!
