It supports SSH. Since that's already in place, not much point in telnet, especially since NAO wants a password. And you prettu much have to go out of your way to install a telnet client these days. That's a bit like connecting to IRC with netcat. It's easy to do, there's some kind of a retro hacker feel to it, but it's just not very practical.
