Thanks to DocArzt for some great detective work in finding the following.
While the ARG server was open to directory listing I found the following caption set that seems to be unused so far. Regard this as a game spoiler.
The caption set is labeled as "Desktop Phone" so I assume this will be one of the messages that Sam receives. Perhaps in the next round of gameplay.
"Sam, it's mum. I just saw you on the telly. What's going on? You're going to loose your job if you keep carrying on like that. I know you probably wouldn't care at the moment, but you look like you hadn't slept in days. I'm worried about your health Sam, physical and... well, otherwise. Can you call me?"
