As a very quick aside, it will be possible to check how your ghosts are doing to a limited degree by pressing Shift + Backslash:

The data available will possibly be expanded in future builds, but I want to the core mechanic pinned down and ironed out before spending too much time on the frills. Still, I figured I should at least provide spawn count and kill count info, so here it is. Note that these stats only reflect server ghost activity: spawns and kills by your local ghosts are not reflected here.
