Last Month the Japanese try to retrive this mod a little bit more. They played in the at 2pm CET. At the moment the gametracker,com Server Monitorring is off. Hope soon they turn it on. The ranking seems to work.
Unfortunatly you are getting into limitations of the game engines, BF is not designed to allow specific people to spawn at a certain point, its team based spawning.
As for respawning where you die, suppose you do a great big leap over a mountain to the finish and explode and die, you would then respawn at the finish. On racing games, the track as a set route which the bots follow, and you spawn at your last known position on this route, which would be either extremely hard, or not possible to implement in a BF mod.
