Very cool! No encryption on the wireless though?

I think I figured it out. It looks like that website maintains a database of all registered exit nodes, and simply sets up a subdomain of the IP of the exit node on record. Going to this subdomain does nothing. Rather, they set the DNS CNAME record to "127.0.0.2" for every subdomain, thus if an exit node is not on record it will not return this value.

If I'm wrong feel free to correct me.

Very cool. I get HOW it works, but WHY does that actually work? Why does an exit node resolved to an IP equal 127.0.0.2?
