With a mod you can do everything you want, unless you want to change engine stuff. You can even make a totally different game.
Actually making a TB mod based on an existing one (etpub or something) would have required less time and effort than making this new tracker, but then you have to tell all the clans to use TB mod, and not other mods.
The way they are doing it now works with all mods instead. About disconnecting, why should you disconnect in the first place?
