I was thinking of a server mod that someone could do. It would work something like this:

Someone records a custom "replay" of a pace car lap. Not a m/spr but a custom one.
Server loads the replay and programmitically drives the host car using the custom replay.
When needed, a replay of coming into or out of the pits can be played before or after the replay so they could drive into and out of the pits.

Recording the replay could be done similar to Kegetys' Ghost Car mod with OutSim. Then to play it, some type of direct input would be needed to control the car from the replay.

What do people think? Can it be done? Who could do it? Do you understand what I mean?
