A new installer tool (xPL Check Package) created and just released. On the windows platform it can easily be added to an installer and it presents a simple interface to the end user to configure some core xPL stuff (firewall ports and hub). If all fails, Mals diagnostics tools have been included as well.
Hopefully this will improve the setup experience for first time users and will enable them to get up-and-running quicker (and reduce the support effort at the same time). So all windows developers are invited to add it to their installers!
If you want to give it a try, get the SMS application, its the first app to include it.
You can download it here or get the source code from the SVN.
(Thanks to Ian and Mal for their support)
