So, this is a remainder from original Aaron's code. I had it removed in one of the latest non-important commits, which were lost during rebase. Will be fixed. But let's discuss the IP address.
Now it's set via the command-line. There would be probably no big deal with getting the IP address of the local machine. However, I don't know how reliable would the gathering of the local IP address be (it must be the publicly visible IP address as it's passed into the CFME appliance to know where to route the events).
