Suggestion:
Can you add this line to the uiconfig.props file so we can just edit it, if need be. I find my self on the hunt for it each time I've installed.

Also another suggestion:
Why don't you place the SERVER IP or NAME in a variable in ONE file somewhere. This would save the installation person from having to go find all the places to change it. Not to say the number of different lines in each file, that may need changed.
Not major, just thinking out loud.
