Trackmania United is one of those things, which i like to play sometimes. More about this game, see also http://www.tm-united.com.
The server can be controlled over a RPC interface which allows to extend to game in several ways. One can add features like a "jukebox" or a records management. Since a while i run my own server, to explore the possibilities. The guys from MistralWS where so kind to give me their modified version of Aseco/RASP, which i changed bit as well. One result of my other "research" is a web site with a status display, track list and several statistics - see also http://playground.arnowelzel.de. Meanwhile the server runs the current version "Trackmania United Forever".
