DL and use locally some parameters from the server, such as track grip,
skins, etc. Why not do the same with the track geometry and car data? They
can even use text files ala ISI; open for anyone to tweak to their hearts'
desire, but if you're racing online you use the common carset used by the
server. Might add a second or two to the log-on, but I don't see any other
big problems. Seems like that would nuke the most common avenues for
cheating, though intrepid souls will always find a way... ;-)
