It does scale properly. If I add an ssh login or a tty# login it still 
shows expected logins +1. Is it possible that I have been hacked? I have 
a few ports open to the internet. I have trimmed this back to only 
include 22 (SSH) but for a while ports 20~23 (ftp, ssh, telnet), 8080 
(apache2), and 6881 (ktorrent) were open. I plan to reboot in a little 
while but I am always sad to see the uptime drop back down to 0.
