Tor isn't playing it up, but they're starting to develop a subset of nodes that aren't published and wont be immediately blocked. Because they're obscuring their efforts I can't find a link for you. A shell account and an ssh socks proxy will still work as far as I know.
But is there an even prime other than 2? I guess not, otherwise it will be divisible by 2.
