A special version of Tim's HOST which removes the restriction that each of the 11 races can play only once in any given game. This allows to assign each of the player slots any of the eleven races. For example, you can play 11 Feds against each other. Games in which this is used are commonly called "SRace" games, even when hosted by PHost which does this way different.

Note that SRace is actually the name of the program to set up such games, not the name of the host itself.
