we (UtCity.net) work currently on an UT RPG Stats System.
It is for Windows Server only at the moment. It is a program, where u can edit the path to the ini file, where your redirect is and where u want to fill in informations.
out of curiosity how are you getting the stats out of unreal?
From what Ive looked at (yet to attempt) there are a couple of options when connecting to something (internetlink, tcplink ect ect)
Also if all thats needed inside ut is to change a port number then I may try taking a stab at making a java/jsp version (with your permission) would be a bit more fun than having to do an address book for a school project.
