highbridge, this would be difficult to do for several reasons.
1) All drivers must be using application
2) All drivers must recieve the /ghost command at the same time (connected externally from LFS I think too, so an LFS connection, along with a normal UDP/TCP connection to a host)
3) The ghost car would haffto be in sync for everyone, which would be hard
4) for Gcar to work, the user needs admin rights.
