 This sounds like a good idea. I looked into `<iq>`s, but it seems they do
 not come with enough text fields (although I could be mistaken). I need
 four text fields to send a message:
 - One for the client ip:port
 - One for the server ip:port
 - One for the actual data
 - The JID of the computer that sent the message

 Unless all four fields can be stuck somewhere in an iq message, this route
 will not work. Maybe with some hacks I could be wrong, but at first
 glance, this looks like a dead end.
