Comment OSX (Score 1) 189
Mac OS X is Unix based so if they are running it there then a command line is accessable. Got telnet FTP and all the other fun stuff. The World Wide Web Consortium document applies to Mac OS 7.5.5, 7.6, 8 etc.. I would assume they are not using OSX because they are running WebStar instead of apache but you never know do you.
