Wonderful Olish!
I'm already working on a PHP application to use your findings to control region -> sim configurations. It's a great help to manage things that easily can modify things depending on lots of factors, like server load, number of active simulator servers etc. Perfect!
Please do file a Mantis request, I bet there must be plenty of people out there that can make use of this!
