If the idea that we should all get identified on the internet takes foot (and I seriously doubt it will), my guess is that we will see an almost immediate fragmentation of the internet.

If you look at wifi maps of any major metropolitan area, they're almost all completely covered with signal these days. A mesh system could be brought up very quickly, with some point-to-point communication to get beyond metro areas. Once that happens I'm sure there will have to be some people who will end up having to tunnel to a "Free-speech zone", but many Chinese citizens are already doing that today to circumvent the Great Firewall. The infrastructure is already in place to escape any attempts at censorship or forced identification now.

Of course, what I'm suggesting is ridiculous... but not quite as ridiculous as recommending we all get on board and verify who we are for every site we visit and every comment we leave.
