AFK Interactive is a real thing. It lets you chat and such without needing the full game client. I'm kind of curious how it can connect to an MMO like this. Does your character actually log in? Does your avatar appear in the world, inert and lifeless?
It's a neat idea, but I came up with something better years ago. It's a little technology I like to call "never leaving the house." Works really well.
I'd patent it, but my mailbox is outside.
