Your computers name?

Well look at that.

I just looked into my command line on my onPC and my desk and I see this:

Looks like it's because both are connected to the world server, perhaps this is chat?

Yes, this is the chat when being connected to the World Server (= green world symbol on the right-hand side of the command line). With the chat command you can send chat commands into the main chat room. At the moment there is only the main chat room available.

That very much explains why the computer in the other room beeps sometimes.
