I think it may even go beyond that, where they have even stipulated what other software could be run on the machine. I do know, for example, that they HAVE to run XP, nothing newer, or it would void their support, etc.. its really insane how companies can get away with that, I don't even understand how for a web app (it uses a Java applet, so I guess it goes beyond a regular "web app", but still..) they can demand this sort of control over the end user's system.
